I have so many, that It'll be a long list, so I'll only go with some major ones. It's gonna sound ranty.
1. Stickers on Fruits and Vegetables. Actually make that stickers in general. Especially when they are on peoples clothes, or even worse, their skin, on something i am going to eat. Not only that, but when stickers are peeling off, and people leave them on things, when they should just take them off? Yeah. That is the worst. Or when people put them on something of value(Computer, iPad, cellphone, Doors in the FREAKING HOUSE!?! OR when they put it on water bottles? There is something called CONDENSATION, people! That shit's gonna get nasty really quick. I cant Even deal with stickers, or anything similar, which leads me to my next big one.....
2. Food wrappers, or packaging. Obviously things need to be packaged to be protected from harm, but once the packaging is off the food, THROW IT AWAY!!! Don't play with it, leave it around the house, put it in a pocket, or anything else Get rid it. This also means individually wrapped candies are one of the worst things ever. Sticky packaging that comes on electronics? Don't just crumple that shit up and leave it somewhere, or stick it to someone, or yourself, now seriously, people. Furthermore, are you eating a candy bar, granola bar, burrito, or even a banana? Peel off the whole "wrapper" and get rid of it before eating it, it's nasty to peel down the wrapper as you eat it. Ugh, I'm about to vomit just thinking about it.
3. Eating Citrus and tomato products together, or, for that matter, having them close to each other at all. People who open up a fresh orange, as I'm eating ketchup is the absolute worst. I've puked on several occasions when that exact scenario occurred. How do people not understand that htese things are not meant to be mixed? EVER?
4. People who are religious because they were indoctrinated, and then never thought for themselves. Wait dare I say that it's the majority of religious people. Not saying faith is bad, but realizing that just because your parents told you that it was the truth, does not make it so. Find your own truths about how life, and philosophy matter.
5. Fanboys who say that other people who support anything but what they like "fanboys." Do to falsified research done entirely be my under improper measurements, I have come to the conclusion that everyone who accuses someone of being a Nintendo Fanboy, is actually a Halo/CoD/Sony/Microsoft Fanboy themselves. People can like things that you don't like! It's not always Fanboyism.
6.People who think that if you are reasonable, logical, and blunt, that you are a mean person.
I can always come up with to tons more.
