One Will Do It

So after a bit of discussion the mob has spoken and one call is all it takes.
This is in reference to getting a number, calling it and leaving a message. It shouldn't have been an issue really, if some one is really interested they would return your phone call and for that reason alone is the reason alone is why there should be only one call.

Why waste someone's time though, has the culture created an image where immediate turn down is now socially unacceptable? Do they fear being called an asshole, or at the very least not have to be called anything in person?

So the new guideline has been set - make the call, leave a message if necessary, and await a response. If they want to contact you they will call you back.

On a side note while I was playing racquetball yesterday there was a statement, which taken out of context could mean all sorts of crude things:

"He likes to put it deep."

This was in reference to the serve I was hitting last night. It would go deep into the corner against the back wall which can be difficult to return.
