I don´t like hypocritical people. People who criticize me on something, and I take criticism very well so I usually implement it into said thing (unless its ridiculous) and then THERE THEY ARE doing the EXACT THING that they criticized me on.
Another thing to do with criticism is I hate when people sugarcoat stuff. PLEASE GIVE IT TO ME STRAIGHT! If I asked for criticism, I´m not going to be offended by your knowledge, if I did something stupid, tell me so I can stop doing that stupid thing. People who sugarcoat things just make it more confusing...
