I answer the door if I am expecting a delivery.
Otherwise I don't bother unless I know someone is coming round.
Why? Because I WFH and don't want to be getting up and down to go to the door for things that I know will be of no relevance to me whatsoever. And in the evenings, again, I don't want to go to the door to have to deal with cold-callers, when I might already be in pyjamas, just out of the shower, in bed, eating, engrossed in hobby, on the phone to someone etc.
Where I live, the doorbell goes several times a day (I'm abroad). We get
- Jehovah's Witnesses very regularly
2.Charity chuggers
3.The Red Cross trying to get you to sign a standing order form
4.Delivery people delivering to other people (who I know for a fact are in the house and refusing to answer... and as I said above, I answer the door when I know I am receiving a delivery. Wouldn't be an arsehole and not bother answering in the hope they would deliver elsewhere)
5.The people who deliver frozen bread from a catalogue (and the frozen veg people and the fresh veg people). One of them was exceedingly rude to me once when I mistakenly answered the door because I refused to take the catalogue - was polite about it too, but I don't want to have frozen veg delivered to my door. Oh yeah, and the fresh eggs people - why would I want them, there's a farm round the corner which sells eggs from a fridge outside. That's where I get mine from.
6.People selling other shit door to door
7.People wanting to collect your unwanted household items/clothes/whatever
And I have a batshit neighbour who comes round to have a go about all kinds of things.
So nope, I don't answer the door if I am not expecting a delivery or a visitor. I don't get people randomly dropping in - everyone messages or rings first.
There is absolutely nothing of interest coming to my door and it's a pain in the arse having to answer to simply say "not interested thank you" or whatever.
