does this sound fair?
my sister-in-law is a stepmother to a very, well, horrible brat of a child. she's 11 and very vindictive and nasty to SIL. i have seen this child in action, and she isnt allowed to play with our kids.
anyways, her sd has a school project and wants to use SIL's craft markers. SIL said no, but my brother thinks that she should let her. or else he would buy the sd her own. SIL is very upset that my brother is being such an a-hole to her. the sd has never once apologized to SIL for anything. it's been a tough year for them.
