Is it normal to fucking hate people when they make sounds as they eat?

I know there's a name for this; for when you cannot stand, under any circumstance, the sound of eating. I fucking hate it. No matter who does it. A few days ago, I thought about yelling at this 6 month old baby for smacking her lips when she ate apple sauce. My Ma will eat with her mouth open when her food is too hot, and I've thought about socking her in the fucking face. Even when they aren't being complete fuckers and eating with their mouth open, just the very sound of eating makes spikes grow into my fucking brain.

I know it's fucked up to be that extreme about it, but over the years it hasn't gotten any goddamn better. I even get angry at animals for it, like dogs with their horrible fucking crunchies and shit. I try and gnaw my tongue when I feel like yelling, but a few weeks ago I cut my tongue up with my teeth so I'm trying to keep myself from doing that anymore.

So anyway please vote and have a nice day for me!
