Question:

What are some good sentiments to write in a friend's birthday card?

It doesn't have to be very poetic....just something nice and sentimental.
I know, I know! I should write it myself, but I'm sleepy, want to get to bed, and finish this.

Best Answer - Chosen by Asker:

"What I like about you is you're always the best you you can be."
"Thanks for being my friend."
"The only reason we need birthdays is because without them, we'd miss a good party!"
"You're the bubbles in my champagne."
"I hope we go on having fun for years and years."
I hope you enjoy your day the way I enjoy being your friend."
