We often see people doing things that aren't quite right - shouting, swearing, maybe even damaging property.
And we wanted to know how you felt when you have seen other people behaving badly.
Does it make you feel unsafe or upset? Or perhaps you don't notice it or it doesn't bother you.
Unfortunately this topic is now closed but there are Comments pages on other subjects on the main Chat index.

"When people behave badly at my school I feel angry that they do this and annoyed that they don't see the sense to stop. It also makes me feel a bit unsafe and I try to stay out of their way."
Helen, 13, Aberdeenshire, Scotland
"I am disgusted with our behaviour in this country. The police and everyone in the community try so hard to keep things all nice, but then some bored teenagers will go and destroy all of them."
Tom, 12, London, England
"I feel scared when I see someone drunk and feel ashamed when I hear someone swear. My friends swear and sometimes I hate it."
Anna, 12, Dublin
"Annoyed. You feel unsafe, but don't let them worry you. Underneath the shell of toughness, they're just cowards."
Francesca, 11, Sedgley, England
"It makes me feel that no one cares in the world. It's just not right how they have treated our once beautiful world and made it a dump!"

"It doesn't really bother me. I just ignore it all and stay out of it so that I'm not giving them a chance to hurt me in anyway."

"In Ireland it's real bad. When I go to school every morning they are all crowded beside the shop kicking the bin down and making a laugh out of hurting the employees."

"Older people are scary when they're drunk."

"I think that bad behaviour affects everyone around you. Some people may only do it to fit in with everyone else so they don't get bullied."
Jessica, 13, Pontypool, Wales
"I've seen a lot of people act badly at school and it sometimes makes me feel scared and unsafe. Loads of people swear for no reason and take pleasure in bullying others. I don't like it and I'd like them to stop."

"In year one my teacher got very angry with me. It made me feel very sad because something was blamed on me that I didn't do. I was very unhappy and in the end me and my teacher were friends again."
Bruno, 9, Oxford, England
"When I see people being mean to other people it makes me upset and it makes me want to tell them to stop, but when I try they just get angry with me. I also hate it when people swear. Sometimes when there are adults very angry it makes me very scared. Luckily it doesn't happen very often where I live."
Milo, 8, Oxford, England
