i asked you today about a scar i had seen on you in the past and you looked to where my finger had pointed and shrugged. "i don't remember." was your reply. so i pointed to another one, on the other arm and you looked there as well "i don't remember." was again your reply.
i paused, and withdrew my hand. then you made the mistake to ask me "where did you get yours?" to which i replied, "you already know."
