U should start playing badmintion at the same place where they play cricket. Just walk in between their game.. speak nothing about your car and car parking.. Kids can be rebelious.. the same way i spray painted my neighbours car when i was kid as he did not like me playing cricket in the parking area..lol.. Occupy the ground before they come in or park your car in such a way where they cannot play.. Although i object to this, as kids who indulge in sports use their energy in a positive manner.. we must encourage sports.. Speak to them politely and tell them to play else where.. try the kind method.. if that does not work.. come back again and say you failed.. I am sure there is way to get rid of pesty kids.... lol. Cheers
