I don't yell or curse at the folks who call, even if I've been yelled or cursed at by them. I usually hang up when they choose to verbally abuse me. Yes, I've had that happen with a representative from a group who wished to sell me insulated windows. I usually explain why I don't need their product as honestly as I can and try to remember to ask them if they'd take me off their call back list before they hang up. The last to call was someone wanting me to subscribe to newspaper delivery. I explained that, in the past, I had spent more time rounding up and organizing my newspapers for the recycle bin than reading them. Many of them were never read. Charities have called wishing donations or to sell me tickets to their fund raiser concerts. I've tried to get them to hire me to open for their various featured acts to no avail.
