Comments
I absolutely hate commenting on other people's journal, I don't know how you people do it. I avoid it at all cost, it always sound silly or I don't have the context and will make a misstep.
I also avoid writing anything that could seem ingratiating, at the cost of not expressing my appreciation for a nice entry or understanding for a situation or commonality of views.
I just don't have the time for making comments and then worrying about them, I already spend so much time thinking how everything I do is interpreted by others. Most of the time, I just end up being misunderstood or ignored.
