Thank you for your replies...actually the cars were properly parked still it's been hit by the ball leaving deep scratches...one time one of the headlights were damaged..some elders try to warn them but you will get a very disrespectful attitudes. Then some cars outside the buildings becomes a warm up benches for them were... imagine that you are the owner of that car definitely you will get pissed...and even the drivers passing down the streets almost burn out their vocal cords to warn them..there is a proper place and a proper attitude..but this kids I dont know if they do have value in their shcool but definitely within their house...
