I do let little things get to me sometimes. At the same time, if its something that bothers you, and you're feeling badly, why does it have to be a "little" thing? They're your feelings and you're feeling them for a reason. I myself, am learning how to communicate more effectively though when someone does something that bothers me. I also think pausing is a great tactic to employ. Giving something time and space and not reacting so suddenly, can really help me, and the other person. I just think, the saying "little things add up for me / you / him / her / them" is kind of a negative sounding saying. Perhaps its just who someone is and that's ok.

I'm actually a pretty private person. At the same time, I'm very open about my emotions with those close to me, and those who seem nice and like they are trustworthy.
