i still can't remember what T really looks like

Someone asked me a little while ago to describe him.. and i could up to a point and then nothing... she asked me if he had a mustahce and i truly did not know.. i once snuck a pic of him while showing him something on my video camera (i later fessed up)... but when i saw him on the video afterwards i was a little shocked. He looked happy and openly friendly.. not annoyed or angry toward me as my mind sort of conjures up...
he asked me why i took the pic and i told him it was because i couldn't remember what he looked like . He wanted to know why it was important to remember that.. and i said so that i could "talk" to him... that's normal isn't it?
i've pretty much given up on trying to hold onto remembering his face or having him with me... it disappears.
