> if you don't get it I don't have time to explain
Bothers me when it's used a cop out (which is most of the time). If you are making an offer, you better be prepared to explain that offer over and over and over again. That's sales baby. The goal is to reduce that but don't make an offer if you aren't going to explain why someone should take it when asked.
There is a difference when those have been standing on their soapbox for months if not years about something and no one would listen so it's time to build.
