say you have a very close friendship. in that friendship you've both fought a lot and you've been angry and not angry, roller coaster almost. you're not friends anymore, you made no effort to salvage the friendship when you knew things were in trouble.
tell me, what reasons would you have for checking up on the person on a daily basis? you've demonstrated that you do not care time and again, so why would you look at their journal, their facebook, ask people about the other person?
