Whenever my MIL comes round (Step FIL doesnt really come round anymore but that is another story)
She will make convosation by asking me a question, usually one that requires more than a yes or no, then when I begin to answer her she starts talking over me or to DH or babay talk to DD.
I find it incredibly rude, but bite my tongue and stop talking. It makes me want to give her yes or no answers and not to elaborate, but I think that would be rude from me.

I have my own theories as to why she does this, I would never voice my concerns re that to DH, but i is beggining to wear me down to the stage where I generally try to stay out of the way when she is here.
