Most of the new girls on the Welcome Wagon fade away very quickly? I'm always looking for "new talent", but have gotten burned a couple of times. I end up going to see one of my more established, older favorites. This is what I think about when I'm bored (and horny).
It is apparent that a lot of the younger providers get into this with an unrealistic idea of what will be expected of them. When reality sets in, they have second thoughts. If you have read some of their first reviews, it should come as no surprise why they bolt.
