well, some of my frustrations have been vented already, but I have a few other things that frustrate me with conversation.
At the Grocery store. I need a produce code, so I look for the sticker, and I hear about a kajillion time a day "it's 99 cents! it's 99 cents!" I grit my teeth every time I hear that, cause I don't give a damn if it's a million dollars, I don't need to know how much it is.
Also, something that comes to mind, is my mom trying to talk. I don't know why she does this, but she has always been like this. She will start a sentance, and then loose her train of thought, or be stuck on a word or phrase she needs to complete it. So your waiting a minute, with her in silence, or saying umm, trying to finish her thought. I will admit, over the years, I just subcaunciosly finish her sentances for her, or at least try to. The problem is, that I end up doing it for other people too, and I think it's kind of rude.
