Only one sponsor has called me in all these years. Musta been a expensive call, from USA to Finland, and to GSM phone.
Telemarketers have left me alone. If they call, and ask if I have time to listen, I say sure, tell me all. Then I put the phone on table and continue to do what I was doing. After 30 or 45 minutes I shut the phone. I don't know if that keeps their line occupied all that time anymore, as we have digital lines (that happened when lines were analog) but I hope so. Nice coffee break from hard calling, lol!
They learn quickly. No calls for a long time.
If someone plays my door bell, I go to a window and look who it is. If it is someone I know, I open the door. If not, I stand by the window as long as that dumbass sees me. I do nothing. Just stare them numbly as long as they walk away. I hope it pisses them off.
