No idea how I'd go about it in practice but:
Hot (and I think single neighbour) is seriously gorgeous. I think he caught me admiring him from the window once when he was scantily scad one morning 😁 I did a very obvious 'quick look away from the curtain' move.
Anyway I see him out and about a lot/we say hello but that is it. Today I ran downstairs to collect something a friend was dropping off with NO make up thinking I'll see no one (but a great hair day) and there he was coming home. I clocked him giving me that up and down body sweep then he actually stopped and tried to talk to me. I rushed off to see my friend and when I came back he was still hanging around and began talking to me again (and checked me out again 😃). I had to leave but I was left thinking 'oh he fancies you too!'.
YANBU - dont ever sleep with or date a neighbour, that's crazy
YABU - It's gonna be a long cold (possibly locked down) winter, go for it.
I have no strategy and am open to suggestions. Just wanted to hear what people think.....
