"the mother - in - law" story

My friend had two teenage children who are big troublemakers. First, they don't know anything, what ever you ask - know nothing so far, they going somewhere, but cannot tell where, boyfriends, girlfriends new every day, then was a new adventure smoking.  My friend and her husband decided to bring his mother from Russia to watch the children. Sold all the property, did the full immigration. Now the mother-in-law in stead of watching the children, is watching my friend all the time, where are going, what are doing, you spend too much, did you make breakfast? And there is no way to send "mama" back to Russia, no where to live, everything is sold. A few Fridays we went to buy a bottle of wine for the daughter-in-law (she is drinking in the bath room) and "a cake for the bitch"(the mother-in-law).
