My niece is twelve and her stepfather's mother is rude to her, sometimes abusive. Both parents work and the stepgrandmother lives next door. My niece has to watch her younger halfsister, which the stepgrandmother favors. Apparently one day the stepgrandmother came over and accued my niece of hitting he sister, then slapped her and threw a CD at her, then stepped on it. the stepgrandmother calls her names and makes comments about her weight and says she is a stupid idiot. The stepgrandmother does some weird things once in a while, like mowing the lawn at midnigth and spraying air freshener outside. My niece confided in me, and I dont know if I should say something. My sister has noticed her MIL favors the other child and tries to make up for it with extra gifts. The husband works alot and is never home (they are welloff because of his job).
