• Whomever is in charge is probably the biggest jerk here.

I find that when I get to new social settings and am trying to figure out each individual and group dynamics, a good shortcut is to find out who is in charge. That person is usually deceptive, controlling, and a bit manipulative. Otherwise, they wouldn't have reached their position. Of course, this is a trend, not am absolute fact. There are social situations and organizations that I have been in where the person in charge isn't a jerk. However, those places tend to be unique and smaller in size.

When picking an item off the shelf in a store, I grab the one behind and bring it forward. I think I'm just trying to make as little impact as possible so I don't get yelled at :/

That a lot of people don't want to understand how stuff works, even stuff they use frequently at home or at work.

I usually don't change for others. If other people don't like how I act, they should just avoid me. If others (schoolmates, etc.) bully me for some behavior, I try to avoid them and mask only if it's very necesarry.
