To the middle age couple trying to cross the 4 lane road.....
It is not wise to run pushing your wife/girlfriend/lover while she is sitting on a rolling walker across two lanes of oncoming traffic to the center median strip.
Watch for that median strip that has reflectors embedded in in the asphalt, when you hit that running some injury may occur.
Then again..... you might have witnessed that first hand when you did a face plant into the asphalt and tossed your wife/girlfriend/lover out of the walker when you hit one of those reflectors.
Then you grabbed the walker, her hand and ran to the center laughing.
Let's leave those walkers to those who need them and it is wise to never play in traffic.
