Um, well....I find that I'm just not good at explaining things, personally. I do tend to be very vague, and I get bored when people go on and on about the details of a situation when the general situation is what is important.
I may not be specific because I find that it's not important. I am only specific enough to describe the time in relation to other events...to give a general gist of the situation in how it affects other things that have happened since then, or something...and the actual situation. But I never get too detailed. I wish I could tell you why I am not specific though. :/

I do get sorta..bored..when people go on an on about the details if they are unimportant.
I don't mind being asked to clarify, but I will often not be sure what else to include...if that makes sense.
