Nine-out-of-10 parents use bad language in front of their kids, according to a new survey.
Some kids said they found it upsetting hearing their parents swear, and lots of them said they had asked their mums and dads to stop.
Others said they had started using words they shouldn't, because they had heard their parents say them!
Bad example
But we want to know what YOU think. Do adults who swear set a bad example, and do you find it upsetting?
Perhaps you think it's unfair kids get told off for swearing, when they've learnt the words from their parents.

"I hate hearing people swear as it has become so common that it is almost like a part of our culture, which is absolutely shameful. Young people, in particular, should not swear and neither should the parents as it influences their children."

"My parents swear sometimes. When I was young it really affected me and I couldn't tell them to stop. Now that I'm nearly in secondary school, I'm used to it and it doesn't affect me at all. They only swear if they have made a mistake."
Nahida, 11, London, England
"My parents swear around me, but they only started after I'd reached a certain age, because we all hear worse things at school and around town as well. It's not really my parents influencing me, as I try not to swear anyway, but don't have a problem with other people if they choose to swear."
Ryan, 15, Birmingham, England

"I suppose parents swearing can have an effect on kids, especially younger kids, because if they hear it more then they are more likely to say it. Luckily my parents don't swear much, but I don't swear anyway - swear words are just rude."

Parents swearing when you're not around is fine - but if you are around it is a BAD example because we could go and repeat it - but I think most children know bad words anyway!
