The 'no reason' feeling..

Have you ever felt irritated when someone said something that has got nothing NOTHING to do with you? Or maybe something that they have concluded or assumed by themselves - the right way or theory? Recently, I don't know why I am easily annoyed by them...this feeling, however, comes naturally..I know I may sound like the mean one but I just can't help feeling so..I think maybe it maybe one of those periods where I am not in a mood for a conversations or crappy talks...Seriously, I hope I can stop myself from feeling like this..I felt as if I dislike what ever that has been said..Hmm...I think its just a 'no reason' feeling after all..just hope that I can stop it asap..
