I’ll Never Forget…Whatisname?
It’s so weird interacting with lovers of loving past. I always find myself on this weird fence of am I going to be a dick to them because they really hurt my feelings and should give them a taste of their own medicine… or am I going to be nice to just be nice? Because once it’s usually done, I’m not one to really revisit, so am I boring and nice so that we can be cordial face-to-face? Seems like the right choice, but that’s so boring and meek. I like the spicy idea that they are unsure if I’m okay with them or not. I like being ambiguously sassy. But then I feel petty and childish sometimes. It’s just so weird! I don’t know what to do. It’d really just be better if they didn’t contact you months later. That would be the polite thing to do. Because, really, what are they trying to get out of being nice to you/hitting you up again?
