Contradictory Situation

Hello Everyone: My weekend was pretty chill. I did a little research into the tutoring center that sent me a recruiter lettee and decided to go for it. I like the schedule flexibility and the pay seems pretty good. However before they talk about the job, I have to take and passed an college entrance-type exam. Why is a mystery to me but whatever. Apparently you can take it in the subjects you want to tutor. I want to see if I can take it in essay writing and history/social studies. Those are my strong subjects and that's what I want to tutor students. I think I'd have more students who need help writing essays. It's not something that comes easily to everyone but critical writing, reading, and thinking are absolutely necessary. Saturday's lunch proved to be another bit of useful insight into Sis's character. Before the meal ended, I let everyone know that the Brit BF was going to be in town and I needed to pause our weekly lunches for the duration. I also mentioned that I wanted to drop by so they could meet him to which Sis asked me not to bring in the house because he's not Jewish. I find that odd because after her FIL's (father-in-law) funeral, one of the BIL's brothers came with his non-Jewish GF and semi-Jewish son. The GF and son went back to Sis and BIL's house and stayed for supper. I'm thinking, if she didn't have a problem with them being in her house, why does she have a problem with the Brit BF? Someone explained to me that religious Jews don't make any real effort to socialize with non-Jews to avoid assimilation. Working with non-Jews is fine but socializing with isn't acceptable. OK, fine, everyone get to have their own religious beliefs. Granted a funeral isn't exactly a time for making pleasent chit chat but if she can tolerate her BIL's non-Jewish GF and son in her house and sharing a meal, why is the Brit BF a problem. Since he's Afro-English, it's tempting to say race is a factor but I don't like tossing out accusations of racism like candy at children. Still, she does harbor certain attitudes that could be considered bigotted. My BIL is more of live and let live kind of person. This situation does require some further guidance.
