I swear too much, but I try & keep it down in front of the kids. The mrs rarely does & I know I'd be upset if one of the girls did.
S'pose I'm jut a bit old fashioned that way, my old man'd hav given us the belt if we'd have sworn in the house, and I sort of uphold that, but I've never had to resort to smacking the kids thus far & wouldn't either.
I suppose it comes down to personal perspective. Doesn't make you any less off a person, but it's still frowned upon by society in general.
