Why do parents let thier kids chase pigeons?

[TitanicWreck]

Whenever I am on the Boston common feeding pigeons, like clockwork, parents with a child will appear, and the child will run towards the pigeons, frightening them...The pigeons, which where trying to eat, would take to flight....I really wish parents would tell thier kids this is cruel, as it does nothing more than terrify the pigeons and cause then great stress.
One might as well have a world where pigeons teach their young how fun it would be to dive bomb towards humans...
Leave our fine feathered friends in peace...
The thing that really bother me are people who try to kick pigeons....
I see teenagers do this all the time, chasing the pigeons and trying to kick them befoire they can fly away..
I saw a grown man in a buisness suit kick a pigeon...
This could seriously injure, if not kill a pigeon...
