Asking Eric: Sister has strong opinions about school choice

Dear Eric: My sister can’t get past the fact that we’re sending our kids to a local public school instead of to the charter school that she sends her kids to. We normally have a good relationship, but this has really become a sticking point for her. It feels like I need to defend public schools every time I see or talk to her, which is nuts. It’s starting to feel political. I’m not a political person. I don’t talk about it. I don’t think she is, either. But this one thing is something she can’t move on from.
