Sometimes, I Just Don't Get People

Earlier today Josh left one of the study rooms at school by (according to all sources) jumping on a table and heading, as the crow flies, straight out of the room. Now I wasn't there so all I have is information gathered afterwards but apparently the issue he had taken was with Megan "existing" (that was his one word answer when I asked him what she was doing wrong)
Now I know this is probably a lot like the Joan Rivers thing the other day, I'd be much less concerned if it was other people involved, but nevertheless, what sort of a problem is existing? Everyone does it, literally everyone, so that is no reason to rage at any one person. Thinking about it, a disproportionate amount of the people I know have a talent for inexplicable rage, this one though is noteworthy for the sheer sustained passion of it all. Generally episodes like these (be they mine, Josh's, Jonny's or someone else's) are either a massive sudden outburst over one specific (generally minor) offence, or a sort of simmering anger (normally explainable, sometimes not)
However it was demonstrated on the bus (in a rather entertaining manner) that this was something spectacularly different. I'll spare you the details but every time I removed my headphones (they were in to prevent me arguing, I'm hardly the perfect audience for an anti-Megan rant) I was greeted by some more (in some cases rather creative) abusive ranting, even a random thing like a child outside the bus or being in Seaton would somehow swing back to the same angry point. I was actually quite impressed, I don't think I could keep being that angry for more than a few minutes. Yet the only reasoning I could get for it was that Megan exists, just like I do and Josh does and everyone you've ever met does. I don't know what the real reason for Josh's anger was (we all know it wasn't "existing") but I hope Megan continues to do it, just for the entertainment it provides.
To justify writing this (I really just wanted to share a story of crazy anger) I'm going to try and crowbar a point on the end here. It's perfectly ok to hate someone, even to the point of table vaulting to get away from them. Just try to have a reason for it, you can't hate everyone, so target your anger at things that shouldn't be accepted, not just existing.
