1. Chewing. I detest the sound of someone chewing. Seriously, you'd be better off to shove a vinegar-coated spoon down my throat than to sit next to me while you're eating. I know that eating has become very much a social activity. And that's fine! Nobody is listening to other people eat if they also are eating. But, if you're the only one in the room eating and everyone else is innocently trying to do their homework, enjoying a quiet conversation, or even watching a movie, go in another room and shut the door!
2. Kissing. Let's all be honest with ourselves. The sound of kissing is horrific. Now, I'll be honest too. I obviously don't care one bit when I'm the source of that noise... But, be respectful of the people around you! It's bad enough to see it coming from someone else let alone to hear it. You all know what I'm talking about. It's disgusting. So, do the people around you a favor and keep the smacking-noises to a minimum when in public. Thank you.
3. Goodbye. I absolutely hate that word. It's awful! I can't even fully explain my detestation behind that word but it's there. Let me tell you. So, please. Don't ever tell me "goodbye". Pick a different phrase like "I'll see you later!" or "Peace out!" or "Hasta la vista!" or how about just "I love you.". All of those are so much better than "goodbye".
