assuming you're not a robot, you miss things about people from time to time. exes. or at least the relationships.
a good measure of how sentimental or dewy-eyed or crazy you're being is how many people you would tell about whatever it is that is making you wistful. i'll tell you this; driving home from a place we went so many times, i couldn't have told anyone any of the things i was thinking (except maybe her, though she wouldn't listen). they were that ridiculous. and at the moment, and maybe now, i miss(ed) them so much.
