I rarely get them now-a-days.....do not call list
when I do, I ask for them to give me their home number so I can call them back....then when they say they can't give out that information I say...I guess you don't like people calling you at home.....and when they answer, thats correct, then I reply....Well neither do I and hang up.....

It makes me feel good.
My cousin will say...hold on a second and set the phone down....and leave the phone off the hook for 5-10 minutes and come back to see if they're still there....you'd be surprised that some still are....
