I did too. Frequency dropped from 15 a day to 4 or 5. Maybe from auto-dialers in foreign countries. I still don't answer the phone.
One hypothesis I hold is that the auto-dialers give up after getting the machine a dozen times or so, but if they even once get a live human, the floodgates open wide. Takes discipline to not pick up when I know it's my wife or daughter calling.
We have a dog toy that is a stuffed animal.
I think it is a hedgehog.
If you squeeze it you get a sound that sounds exactly like a human fart.
When I get a telemarketer on the lines these days I squeeze it.
If they say anything else I squeeze it again.
Fun for the whole family!
