Safe "NOT"

As you know, dear Pre-K families, Pre-K friends take every morning a walk to the Public School Playground to play climbing, sliding, running and exercising. One of such days was a very windy day. Sometimes wind gust was strong enough to pull off boys' kippas from their heads. On Pre-K friends' way back to school, one friend's kippa was blew off by wind on the road. The friend ran after his kippa !
OH-OH! It was a very dangerous choice!
In school, friends discussed why this situation was dangerous and what should be done to make it safe. Friends learned that roads are made for cars which are big and fast. If anything of ours (a kippa, ball or anything else) lands on the street, we should NOT ran on a street to get it! This "NOT" teach us to be safe!
What should we do? Friends said that we should ask an adult to get it for us!  That will be a safe choice!
