It's good to be polite to one's neighbors.
Ping is in his front yard pulling some weeds when his neighbor Frank asks him what he's up to.
Ping wants to tell Frank what he's doing.
Ping tells Frank that he's pulling weeds out, and he thought today was a good day to do it since it's not too hot.
Ping tells Frank that clearly he's pulling weeds and asks Frank if he's in possession of a set of eyes or a brain?
Frank tells Ping that it's a good idea to do it today and asks him if he can help.
Frank is insulted that Ping is responding so callously when Frank was just trying to make friendly conversation.
