Lack of appreciation.

I'm restraining myself from sharing stuff with you since you don't make signs of appreciation. "Thank you" is a word you seldom use, and you've never thanked any song or poem I've gave you. (Songs and poems made specially for you).

I can't control my feelings or avoid thinking of you... But sure I can stop myself from beginning interaction. I know my silence can last forever... And so will yours apparently. I know for sure you don't and won't "miss" me...
