I hear ya, starving folks don't need my clothes.
I do feel for the telemarketers, it's got to be the worlds crappiest job. You either don't care or you have to have a hide thicker than a mammoth to do that job.
We do get a lot of tm calls at the veterinary hospital where I work and they are a horrid nuisance for us. But we just tell them no, or if we're super busy, just hang up. No offense, but bleeding patients take priority.
I did have a tm stalk me a few years ago. It was not fun. The dumb thing is, his phone# actually showed up on our caller id. So I did a reverse search lookup and found his address. Then my dh called him back and told him we knew where he lived/worked and if he called again, we would call the cops and turn him in for stalking. He finally quit.
