What sucks is when you have ADHD and you actually have something you hold a grudge over, your motherfucking attention will not allow you to forget that grudge.
It'll be 18 years later and you'll remember the time that thing happened and you'll be pissed off as if it were happening right now, but it will be nothing but impotent, tear-inducing rage because you have no outlet for the frustration that still feels raw and fresh like it's happening to you right now this very instant.
