Remembering someone I miss on Valentine's Day

In this swap, we will be remembering those that we miss for whatever reason. You will be writing a letter to your partner, about who you are missing this Valentine's Day. In this letter please tell who you are missing, why you are missing them, three things you have learned from this person, and what you would like to tell them.

I find that sometimes it's healing to write your thoughts so there will be no length requirement on this letter, just please, try to make it more than a few sentences.

You will have 1 partner for this swap. No 1's or 3's in the past 6 months, newbies are allowed, and no ratings less than 4.98. I will angel, but please don't flake-it's not nice!
