If it’s really warm, you can’t really blame her. It’s just a brief period during the year when she’ll be like this, so what’s the harm? Not sure where you live, but I’d wear nothing but my underwear where I am right now.
I’d say the best course of action would be to say nothing and just ignore it. If my step father would say something like that to me, I’d feel a bit uncomfortable. It’s up to you though, you know your family better than we do.
That is good to know. Tried the free version of Roll20 before, and it definitely felt lacking in certain areas. Oh, and thanks for letting me know about the sale! I’ll definitely keep an eye out for that one :)
