Please explain

i must admit the pictures are cute, but why? why do thousands of people let their children trick or treat? you basically are teaching your children how to beg, why? i can honestly say growing up i trick or treated one time and thought it was the stupidest thing ever....begging for candy. and the money that is spent on a one time trick or treat costume? why do some parents allow their children to dress up like ghost and goblins? i really don't understand it all!!

we have no cute pictures of halloween costumes, but of grandpa and grandma dewey with the boys...enjoy..
