Every ******* day!
Gloria for me and my schoolmates (and now my friends) 'bad words' were just 'funny words that are forbidden for no obvious reason, and exactly because of this are absolutely funny'. It is uncommon attitude:) So we rarely swear with them (and rarely swear at all), we rather joke with them.
It hapepns that i swear, indeed... but it also happens that I get shocked with their use to express a negative enotion: for me they are rather connected with something entirely happy:)
"With my family, I swear quite often..."
I expected a continuation like this: "....but with my firends in the pub or while playing football...."
I would say quite often in my own langauge and also often in English.
It depends who I am with. With my family, I swear quite often, but in public I usually watch what I say.
