A Ghost of Christmas Past

While I was getting my mocha at the coffee shop, I saw someone who looked like this girl that an ex-boyfriend slept with (I think, but I'm not totally sure) while we were dating. The person at the coffee shop was not her (unless she hasn't aged in 15 years), but she looked like her. Needless to say, back when it happened, that girl was someone I didn't like very much. I wasted much time and energy on her and him. When I saw this person, I realized though, how it didn't matter to me now. I couldn't even remember the name of that girl. Wow. At the time, I never thought I'd not care, but now I don't care. It's truly amazing how time does heal all wounds and how much life changes. That ghost no longer haunts me.
