I work in my garden office round the back of my house.
I have a front door with a bell which is linked to the office, and a back gate which is usually bolted.
If I am expecting someone I will tell them to come round the back. I might unbolt the gate if I know when they're coming, or they'll knock on the gate and I'll hear them.
Some people think it's OK to try and enter through the back gate w/o me knowing they are coming and I find this uncomfortable and inappropriate.
The Hermes guy does this now. There is no need. If he rings the bell I will go to the front door.
A chap who gave me a quote for some work just tried to open the gate, to ask if I got his quote. It just feels like they're entering my private space w/o being invited or letting me know they are there.
From their POV, I imagine they are thinking that because they know I am in my office, they're saving me getting up to answer the bell or gate.
For disclosure, there were many years when the jangle of the gate meant my now ex was back and would mean my peace was over and the emotional abuse would start. It wasn't until after he left and I started to get a very negative physical response to the noise of the gate that I realised and appreciated just how awful it was. Only a couple of friends know this and will always ring or knock.
I always announce my arrival at someone's house, even if that's just a coooeeee over the fence when they're expecting me. I would never just enter someone's property.
But I can't decide whether I'm being uptight.
