Very regular telemarketer caller.  We have them blocked, still my system allows the telephone to ring once.  I rarely ever answer any telephone calls without at least screening the Caller ID display. At least I have the small satisfaction of never listening to their scam spiel.  Still, these calls are annoying.

I just couldn't believe that telemarketers actually convince anyone to buy anything or give up any personal information.  Well, until my mother-in-law developed dementia.  She has no idea who or what these people are doing or talking about.  She also began receiving torrents of charity pleas for money in the regular postal mail.  So now, we handle her finances so she can't get taken by any of these scam artists.
