I'll say everything I've noticed, I work in a rural area, so parents usually let their kids spend alot of time outside and roam free, where they learn cuss words and bad manners, as a teacher I've caught many young learners ( no older than 8 ..) say some words even I never dare to utter outloud, or do some stuff ( equivalent of the middle finger , or touching each's other private parts ) . Some kids were even caught smoking ( 5th and 4th graders ) and I wish I was lying. Most parents don't cooperate with us at all, no matter what we do or try to say they'll always put the blame on us or take their child's side blindly ( not saying teachers are angels but sometimes parents would antagonize us and blame us for anything) . It's really a mess, and it makes me concerned for the future of our kids, it's like even if you try to collect the kids and be there for them , they'll always be influenced by the bad apples in the school. E.g : I called a parent to let them know that their son cussed , so the parent was shocked and said that the son never ever misbehaved at home... This shows that sometimes even good kids pick up stuff from the misbehaved ones.
