Totally understand.

I get the "mum, mum, mum". I respond and then I get dead silence. I have to prompt her to talk. Then she finally starts to talk in a stuttering way "well, you know, you know, that show with ....., well you know the other day how it...." Drives me batty.

Some days I am patient, but other days, I am just honest and say that she needs to get to the point. I know I need to handle it better.
