Why can't I stop responding to the SMSs of someone who
(1) takes it for granted I'm going to sleep with him?
(2) is never awake the same time as me?
(3) known to be a player?
(4) moves too fast for comfort?
(5) does not understand that "I miss you so much it hurts" is a joke?
(6) thinks "miss" is spelt as "miz"?
(7) uses the phrase "I heart pain"?
