I so much disklike people who are not hosnest. Showing you a side of them and being the exact opposite when you are not with them.
I actually hate it when people are fighting and one of them is shouting or arguing so loud. Something like this happened 2 weeks ago and one out of the guys arguing was lousy. I tried to tell him to chill but he raised his voice at me. I left their presence because I couldn't stand that noise.
