history: I have an older sister that is always comparing our kids as if her kids are smarter. My older sister is always comparing our children. Oh wow_comma_ that's kind of rude. Yes it is upsetting_comma_ because she alludes to her children being smarter and more well-rounded than mine.
current: Have you brought it up to her? Maybe she doesn't realize she's doing it.
next: I have not had a conversation with her about it. However, I know she does it on purpose just to get on my nerves. She has a history of getting enjoyment out of messing with me and now my kids.
