It might have taken us a while, but over years of having mutual friends, going to the same events and liking the same things we've arrived into this day and date, where I can proudly call you a close friend.
True, you're almost past your teen years- As Israel sees it you're already a responsible adult (pfft)... But don't let that knowledge discourage you from the things you love, the things you enjoy doing and being the goofy, gleeful optimist you are.
You're great and you have many great things ahead of you, I wish you a happy birthday. Always shine this bright.
