How Can Communication Difficulties Effect The Child Behaviour?

Well.. If the kid can't communicate with his/her parents it means she/he is afraid of what the parents might say.. Sometimes its good for the parents to come to the kids first.. Well anyways.. If the kid doesn't talk to their parents first.. Then they get stressed out and frustrated..and when i'm stressed the last thing i want is for a teacher to scream in my face.. I get frustrated and scream right back.. That leads to trouble.. Then the teacher tells the parents wants going on and the parents smack the crap out of the kid! The kid did nothing wrong! He/she just got frustrated!!! Thats normal! I don't understand parents and they don't understand me! I guess thats why i'm grounded and got screamed at by like 5 different people..
