If you don't work from home, you probably have no idea how many door-to-door salespeople there are out there. I've been amazed - and appalled. We are inundated by energy supply companies asking to see our heating bill, to see if we are "eligible" - love that bit - for them to sell us something. Even if I were in the market for a new energy supplier, I would never buy anything that was sold unsolicited door-to-door. I find it so intrusive, and so irritating.
I try to be polite, but the effect is cumulative and my patience is wearing out. Last week I said, "We're fine, thanks," and the guy started arguing with me. I said, "We're having dinner, and you've just interrupted us. Please go away."
This afternoon I said, "Do you see the sign next to you?" I pointed to this --
-- and said, "That applies to you, too. Have a nice day," and shut the door.
I don't answer the phone unless I want or need to, but I can't ignore the doorbell. If it's a young person collecting for charity, or a neighbour who needs something, or a package delivery, I want to answer the door. But I don't know that until it's too late.
Somebody needs to invent caller ID for the doorbell!
