I’m going to come clean: Sometimes when I’m bored, I look up my exes on Facebook and MySpace just to lurk around their pages and see what’s new. It’s not one of my best habits, but what can I say, I’m imperfect — and a tad bit nosy. I never make contact with them, and I have no interest in ever seeing them again, but I guess I just like to stay in the know. I may be biased, but I consider this kind of curiosity totally innocent. Do you agree? Ladies, do tell, do you ever check out social networking sites to keep track of your exes?
