Giving niceness a try

I noticed how brutally honest I am lately; this is not necesarily a good thing. I believe that in order to live in a peace world environment you must learn to accept people which I find so fucking hard to do at times because most people are rude, creepy and annoying. I have somehow developed this cruel honesty towards those people. I know that telling someone the truth is admirable but I think I've taken this to another unnecesary level. I am mean, like I would tell someone straight up that I do not want to sit with them or talk to them period. Usually because they give me a weird vibe and I simply really don't want to talk to them but I feel like maybe I could be nicer about it? Maybe I could try to sugar coat it a little bit at least in order to not get stabbed or punched in the face or something? I could give niceness a try.I could try to not be rude even if people are being rude, I mean isn't that being the bigger person? I'm just so aggresive lately, so hostile. I don't know where it came from but to certain people I'm simply a bitch to and I cannot help it. Like last night, I'm talking to Eri and we are obviously in this deep conversation and some dude interupts me to ask us if we are singing or something. I just looked at him and said "we are talking" I mean, what the hell? He was so rude. I'm sure he didnt' mean to interupt us or whatever but shit like that piss me off because I seriously doubt he was there to really ask us whether or not we were going to sing. He was there to try to get in our pants and waste our damn time which I put a stop to right from the start. I dont want to change who I am, which is this...I'm a bitch at times, but I mean well. I might be harsh but I'm still friendly to those I consider worthy. I dont think I'm the best, but I know what kinda of friend I am, I know I could blow your mind, I know my energy could pick you up and take you around the world therefore I try to surround myself with people who are equally powerful. Still, I could perhaps be nicer, say "I'm sorry, we are talking right now" instead of the hard cold response. Maybe I could try building more friends instead of shutting people down immediately. I think that you live and learn and this is me, learning.
