Watching and hearing people eat drives me crazy!

this is my pet peeve of all freaking time... I want to punch someone in the throat when I hear smacking.. My dad does it the worst.. Eating his food without a care in the world... I literally have to get out of the room or quickly finish what am doing and leave....when I was younger i use to lash out at him cause of this I couldn't help it... It's the nasty smearing smacking sound that gets me... like when someone eats a mouth full of bananas with there mouth open.....I could shoot someone....omg and my dog has just started making this kind of noise with her mouth I think it's dry mouth... I kick her out my room when she starts to do this... I really wish this didn't make me crazy but it totally does
