Letter 13: Funny birthday letter for best friend female
Happy Birthday to the one and only Queen of Quirk, Duchess of Dork, and the Supreme Ruler of Sass Planet! I thought it crucial to remind you of a few things. Firstly, it’s scientifically proven that people who have more birthdays live longer. So, congratulations on being one step closer to immortality! I’m starting to suspect you might be a vampire, but hey, you’re doing fabulous, darling!
Remember, with age comes wisdom. Or, in our case, a more sophisticated level of craziness and an enhanced ability to not remember why we walked into a room. But fear not! I will be here, as always, to walk into rooms and forget things with you. Together, we’ll be unstoppable… or at least, very forgetful.
This year, I hope your birthday is as incredible as the time we [insert hilarious memory here – like, “tried to bake a cake and ended up with a new species of burnt crustacean”]. May your day be filled with laughter, cake (not burnt, hopefully), and maybe a little bit of adulting (just a tiny bit, we don’t want to overdo it).
Let’s raise our glasses (of wine or maybe just fancy water, we’re classy like that) to more adventures, more ‘why did we do that?’ moments, and to another year of being fabulous and slightly weird. I wouldn’t have it any other way.
Before I sign off, just a little wisdom from one best friend to another: Always remember to keep your chin up! Otherwise, you might walk into a wall or, even worse, miss spotting a cute dog on the street. And we can’t have that, can we?
Here’s to you, [Bestie’s Name], the [insert a funny compliment, like “the most magnificent unicorn in a field of horses”]. May your birthday be filled with all the joy, happiness, and weirdness you bring into the world.
Love you more than [something funny and relatable, like “chocolate loves to find its way onto my favorite shirt”].
Here’s to another year of fantastic adventures, questionable decisions, and all the inside jokes that nobody else gets but us.
Happy Birthday, you magnificent human!
With all my heart,
[Your Name]
Letter 14: Funny birthday letter for long-distance best friend
Hello [Best Friend’s Name],
Happy Birthday from across the miles, my beloved partner in crime! While I’m over here and you’re over there (probably doing something less cool without me), I wanted to ensure my presence is felt in the form of this mildly hilarious, slightly sappy letter.
First things first: congratulations on surviving another year of this wild ride called life, especially without me physically there to remind you not to do the crazy things… or to do them and make sure we have a story worth telling. I guess you could say you’re officially [insert age] years young and still as fabulous as the day we decided we were the modern-day version of [famous dynamic duo, e.g., “Batman and Robin,” but funnier like “SpongeBob and Patrick”].
I know it sucks that we’re celebrating your special day with more miles between us than we’d like. Still, let’s not forget the time difference that lets me wish you a happy birthday before anyone else (because, let’s face it, being the first is what truly matters). And, yes, also the fact that I can technically celebrate your birthday twice—once on your time zone and once on mine because you deserve a birthday that lasts longer than my last diet attempt.
This year, I hope your day is filled with all your favorite things: cake that’s more frosting than sponge, messages that make your phone buzz more than a bee on a caffeine high, and perhaps a surprise or two that makes your day as unforgettable as the time we [insert hilarious shared memory, “tried to karaoke to songs in languages we didn’t speak”].
I’m sending you a virtual hug that’s so tight it might crack your back—consider it a birthday adjustment from afar. And remember, calories don’t count on your birthday, so please indulge in that extra slice of cake for me. If anyone asks, say it’s medically prescribed by Dr. [Your Name], specialist in birthday-itis and fun.
Until we can celebrate together and create more memories that are too outrageous to share with anyone else, know that I’m with you in spirit, toasting to your health, happiness, and another year of our unbeatable friendship.
Here’s to you—may your day be as wonderful as the idea of me skydiving without a parachute (because let’s be real, that’s the only way to truly feel alive, right?). Can’t wait to catch up and hear all about your adventures. Until then, keep being the amazing, slightly nutty person you are.
Happy Birthday, my dear friend! Let’s plan something epic for when we reunite, like a world tour or, at the very least, a tour of every dessert place we can find.
Yours,
[Your Name]
