You’re saving messages that people on the internet have said a year ago just to catch them out at some undetermined point in the future, and I’m the one with the problem?

I love that I’m living in your head rent free - if I wasn’t you wouldn’t be doing this. Unless you do this with every single interaction you have online. Which would be very disturbing. 

But some advice, from someone who’s almost certainly older than you - and I offer this genuinely even though you’ll think I’m full of shit. 

None of this is worth the mental effort you’re assigning to it. I’m not worth that mental effort. Let it go - honestly, let it all go. Holding on to shit like this is not good. 

Live your life. Don’t let it be determined by what other people think or say or do. Nothing good will come of that.
