Chivalry

I know that the times of chivalry were also a time of brutality and ignorance, but with this age, it seems like the ancient art of chivalry has died. We still have the brutality and ignorance, but there is little to temper it anymore. Moz went out with my Dad the other day looking for a place to house his business which has to move because the building he's in is too expensive to stay in. The following day, he went to help his stepfather. Quite jolly, he came back and announced that he'd found the new home of his business. At first I was relieved but when I started to question him it turns out that the location in question belongs to my MIL (!!!). Now, this is the man who has said all along that we should have nothing to do with his family. It seems this doesn't apply when they are some use to him. I told him fine, have dealings with her (even though nothing good will come of it) but leave the rest of our family out of it. This apparently isn't good enough and we are all expected to play nice again. Perhaps it's selfish of me, but I'd just gotten used to the idea of not having her in our lives, of not having huge amounts of stress to deal with. I know it's not easy to find a place for his business to go, but my MIL? Really? After everything that has happened in the last few months?
He said he was tired of her blaming me all the time and the way she treats us.
Chivalry is most truly dead in our house.

That being said, I think I'm going to take up sword fighting (which has nothing to do with MIL, honest).
