Thank you. I live in a suburb of London, and foxes are just very common here because of easy access to scavenging food. It doesn't concern me - while they're certainly much more used to people than they used to be, it takes very little before they're scared off. They're wild animals so I wouldn't approach them, but as long as you don't actively corner one I wouldn't worry.

The pictures where they're looking at me and remaining relaxed are all with the garden door closed - I don't know if it is that they can't smell me or that they understand the door is a barrier, but there's a big difference in their demeanor then. If it's open, they will not come close, and they'll run away at the slightest hint of me moving toward them.

One funny thing is that it matter a great deal if I look at them - I realised it's a lot easier to take pictures of them if I make sure to look at my phone screen at an angle while taking a photo instead of at them, because as long as I'm averting my eyes they seem to see me as much less of a threat.
