Happy birthday to my fave human on the planet! Love you, mean it!
It's your bday but somehow I get a gift (it's you, you're the gift!!!!).
HBD, best friend! Just because you're a year older doesn't mean we have to grow up.

Ily to the ends of the earth, best friend! But you already knew that.
I'm for real obsessed with you, bday gal! Don't ever forget it!
Sorry to get all cheesy, but ilysm and can't imagine this crazy life without ya.

What to write in a birthday card for your colleague

Block your calendar! We're going out for bday drinks!
HBD to my work wifey! I don't know how I'd survive this place without ya! (No really, I'd quit.)
Happy birthday to my coworker-slash-therapist!
Birthday Slack huddle in five, k?
Happy birthday to the one person I actually like at this office!
Birthday coffee on me! (Jk, we're hitting Pret with the company card.)

Ilysm, birthday babe! Can't wait for all the birthdays to come.
Fr, you're the hottest bday [girl/boy/partner] around!
You can unwrap your present later...
Happy birthday, baby! You don't know how hard it's been not telling you what I got you!
You blow out the candles and I'll handle the rest 😉.
Happy birthday to the only boo my [dad/mom/parent] has ever actually liked! That's reason alone to celebrate!
Prepare for the best birthday of your life, baby! I've got plans.
Happy birthday!!!!! I got you the best gift (hi).
Happy birthday to the love of my f*cking life! You deserve the world and I intend to give it to you one day.

I already got you the best possible birthday gift: me! But there's something in the post, too.
Happy birthday, [mom/dad/parent]!! Thank you for letting me call you at every minor inconvenience!
I know your birthday won't be perfect (because I'm not there, obvi), but I hope it's as close to it as possible!
Thankful for every year with ya! Happy birthday, [insert nickname for your parent]!
You're the reason I'm so spoiled, but now it's my turn to spoil you! (For today only, though, okay? You taught me how to budget.)
Birthday dinner on me (for once)!
Thanks for being my best friend and [mom/dad/parent] all wrapped in one! Happy birthday!
