Futurepotus – I was just explaining why LB seemed to think that they do and what her question seemed to be based on. I wasn’t saying that I agree.
I have never seen such an umbrella, so I don’t feel qualified to have an opinion. It is possible that the whole idea is ridiculous but I don’t feel comfortable saying so if I don’t know what we are talking about. But I certainly don’t want to give over the impression that I think there may be something wrong with it either.
