“It Bothers Me”

My mother and many of the women in the neighborhood I grew up in, used to put their hands together, slapping them in an up and down motion as though they were dusting off something, then they would say, “I wash my hand off of it.” This meant that they were no longer going to say or do anything about a particular situation.
Recently, I have been seeing so many women on television… dusting off their hands. , but they are dusting them over food… It bothers me...
