It's interesting that the top two things that people hate are rudeness and mean people. I agree. Who wouldn't hate that? But, then, there's so much of it around!! Why, I wonder!
About belching & burping, nose picking, bum scratching, hairiness, etc. that doesn't bother me if it's a friend. Those are all endearing qualities IMHO! Also, people who spit when talking, they are likely to be passionate about what they're saying. I just try to dodge the wetness and keep on listening! Bad breath and bad hygiene don't bother me; I probably give back in kind!
So, there are people who detest immigrants? Why? aren't we all immigrants? I don't think there are many Native Americans on BetterMost (maybe David, partly!)
Hearing someone use the bathroom: now that is funny. Some guys sound like a horse when they let loose! It doesn't bother me at all.
