When people do things to benefit themselves at the expense of others. An example would be that today I learned my friend's fiance was mining crypto currency inefficiently with his gaming computer, racking up the electric bill of my friend's parent's house that he does not pay for. So basically, up until recently after he was talked out of it (I hope anyway), he was making the parents pay a good bit more in electricity while he basically pocketed free money for himself. If he payed for the electric, he would realize that he's better off buying the cryptos instead.
People who hide their true feelings, despite how obvious they are
People who pretend things that happen didn't happen just because they HAD A CHANGE OF HEART
People who are unable to handle rejection, take a no for an answer or learn how to remain as friends
Manipulative people who string you along knowing what your feelings are. Getting your hopes up to smash them with a hammer for fun and games, hypocrites, and liars
When people send out "prayers" to help, like for natural disasters for instance. Praying isn't going to do anything for those flood victims, it's a lazy way for someone to claim they're helping.
A pugs face and anyone who thinks the deformed mongrels are "cute xD"
People who throw trash on the streets, even small envelopes or cans , gross bastards
I'm gonna send you photos of streets in my neighborhood... they throw anything and everything on the street corners man, even animals aren't as dirty.
(Weirdest so far was couch cushions, baby diapers and magazines)
