When people expect something from other people but will not do anything in that way, example below :
When people make a "bank" room but do not put a pass: yeah people can join, you gave the gun to get shoot man
When people trade basic stuff by dropping it on the floor instead of using trade window: yeah people can rob you, you could as well open your wallet and flap it in the street
When people ask basics informations that they could find... anywhere, literally. And not only google, pso-world, universps are your friends, but this very forum got a lot of data too
When people make 200 runs and feel that only them are right to complain about not finding more than one of a certain item whose drop rate is 1/3xx, yeah right: well don't complain when other complains about not finding something, cause you're the same if not worst (this sentence is awful, I will complain about it in a brand new topic later on)
