Lol...That's a good question. Ya know, I'm only now realizing just how much I do it until you said that I think it's because I often I end up expressing a lot of "sidebar" thoughts that are kinda related to the preceding sentence, but not completely (same thing during my personal interactions in reality, lol....Dang it I just did it again!) My ADD brain often wants to get multiple thoughts out at once; but then, my mild OCD drives my compulsion to keep the paragraph on one subject. Could be grammatical laziness too...wanting to express quickly yet not having the patience for using the proper syntax to put the thoughts together, lol
P.S. I moved this to banter so we wouldn't crowd the thread...despite the dirth of optimism at the moment, lol
