It all depends on the specific reason that @Jumpinbare wears clothing in public. If he likes being nude but doesn't like being seen that way by others, you have a point. If he would love to go everywhere unclothed but conforms to social custom, why be worried about an emergency? If he's forced to be seen like that, so be it.Another saying we have in my family is, always be dressed for an emergency
Imagine there's a fire, or earthquake, and you have to leave the house, immediately!
I'd rather have a t-shirt and shorts on
