Last night I received a skype call. The first thing the caller did was transmit "AVI?" or some such abbreviation, to request my statistics. I responded by typing something like this: "You called me, I didn't call you. Under the circumstances, it is a violation of etiquette by beginning with a request for AVI." If one answers such a question and the caller doesn't like the "stats," probably he will immediately disconnect. The rudeness of some callers is astounding. There may be no solution to the widespread rudeness which seems to be on the increase.
