My experience is mixed; I have a lot of sympathy for the honest folks stuck in a bad job and since giving up our land lines we don't get a whole lot of scammers on the phone anymore. We do get the missionaries at the door from time to time though and they're invariably well-intentioned super polite kids. Lately I've taken to trying to get them to crack a smile. It's not easy to get them off script but when they do their smiles feel good ... I also had two young men helping with yard waste last summer; traipsing across the yard in their white shirts and black pants; and two women who met me in the driveway this January who passed me their bundle of pamphlets and picked up snow shovels. Neither set came back though .... hmmmm
