I was vaping in the garden standing by my back door, had short shorts and a vest top on (I'm obese so would be very uncomfortable being seen) as no one can see into my garden otherwise.
My neighbour opened her upstairs window and leaned out of the window to look at me, I was on the phone so stared back, she looked very embarrassed and closed the window again.
Would you bring it up with her? I found it really strange she would even want to do that as she really has to stretch to see me.
