Oh exes. You'd think you'd be rid of them once you're not officially together, but sometimes they creep back into your mind. When you look at the calendar on your former anniversary, for example, you might spend the rest of the day remembering your first date.
Do you remember ex-boyfriend's birthdays, and if so, is it rude to not wish him well?
I weighed in with my two cents, saying that if you remember, it's totally cool to send a quick email or Facebook message. But, if you don't want to initiate contact, I think it's fine to let it pass and just send happy thoughts (or the opposite!). What would you all do?
