Sidewalk Chalk Art Against The Rules In Stapleton" from CBS4 Denver.
In a world with different poeople and opinions, is the best course of action to just restrict, restrict, restrict, eliminate, eliminate, eliminate, because some people are "offended"? What do you do when being offended isn't a reasonable reaction of a reasonable person?
I think you should tell them that there concerns aren't reasonable, a/k/a "no!"
For what it's worth, 4 households on my block (yes, with girls living there or visiting their grandparents) frequently do chalk art.
Just like I am fine with street games ("Street Games Citywide Festival" webpage, NYC Parks), I think we should recognize that the point of living with other people is to learn how to interact, get along, compromise, etc.
