When we were young, you made it clear that you were attracted to me. You asked me out on dates, you tried to be where I was, you told friends and teachers that you were interested in me. I gave you no attention. I ignored you. I avoided you. I quit music lessons with a teacher who wanted to encourage our relationship.
Friends told me that you were miserable. They told me of a time you were sitting in a tree in tears because I'd preferred to be out of town with my family. I wanted to be at the ski slopes, not because I loved skiing, but because that's where the "cool" kids were. You didn't ski, and probably couldn't afford it. Even though we had similar interests, I was unaware of that. I was unaware of you. I paid no attention to who you were. I had no good reason for this at all. I had no reasons that I can think of. Perhaps I didn't have respect for anyone who respected me. I am sorry that I was so self-centered and so oblivious to how smart you were, how musical, how kind you were. These were all qualities that I valued then, I certainly value them now.
Now I regret my behavior. I'm sorry I caused you sorrow. I'm sorry I didn't appreciate your good qualities. Even more, I regret missing out the opportunity of having a relationship with you. I have missed having you as a long-time friend and wish I'd forged and maintained a connection with you for all these years. I certainly appreciate who you are today. I'm sorry.
