Rudeness

On not returning voicemail in the digital age.  A lot of the new phone technology basically just enables rudeness.

I don't return calls unless the person leaves a voicemail.  No voicemail means they don't want a call back.

When I was young, I didn't think manners were important.  The older I get, they seem to be one of the few ways people can acknowledge on a day to day basis, we live in a civilized society and are not just a bunch of apes living off the tits of men and woman who created civilization.
