I first met you years ago, we were in 5th grade together and I remember always thinking you had the prettiest smile. There was this one time a friend of ours (I don't remember who) told a joke that made you laugh. I remember immediately thinking "I wish I'd told that story, I wish I was the one who made you laugh." It's been 9 years since those halcyon days and I'll always wonder what would've happened had I told you how I felt.
Sincerely, The Boy Who Always Sat In The Corner Seat
P.S. I still remember walking back from school together.
P.P.S. I'm revisiting this years later and now you're engaged- I don't think I'll ever share this with you but in the event that you do come across it, I wish you nothing but the absolute best. You deserve it.
It's been interesting seeing you grow up. I'm proud of who you are and I'm excited to see all you'll accomplish in the coming years.
