manage a kite on his own...
unless you want to watch the kite fly through the air when he decides he's tired of hanging onto it and lets go;
unless you want some exercise running after the kite's string as the wind lifts it higher and higher in the air;
unless you want to watch the kite go through an evergreen thinking for a second that there is hope of rescuing it;
unless you want to watch the kite be carried through the evergreen to the power lines;
unless you want to watch the kite string get caught in the power line while the kite continues to fly high;
No, it's probably not a good idea to let a three year old manage a kite...
unless you want your blood pressure to go up while watching the kite fly over a very busy road as the string is still attached to the power line, praying that the kite doesn't take a nose dive right into an on coming car or motorcyclist, causing an accident;
not unless you want to call the local power company and wait impatiently until they get to the scene;
not unless you want to watch nervously the employee from the power company be raised in the bucket to untangle the kite string from the power line and whip the string across the road hoping not to hit a car;
not unless you want to watch your husband dodge traffic to fetch the kite that landed on the roof of the assistant living place.
Luckily nobody got hurt and the kite seemed to have survived as well. But enough drama for one day!
