Speaking as your sweet SIL (<3), I'm glad you didn't go there in your head because I wasn't miserable at all. Poses were challenging at times and it was an interesting class, but I didn't have a single moment of misery. So I'm glad you didn't let yourself worry about that.

Regarding the theme of this post, I've also been working to hold that kind of space. Had a conversation with someone yesterday which consisted of, "I'm going to let them have their feelings about that and I'm going to have my own feelings over here. Their experience doesn't need to be my business." high five
