Everything

This is everything I know about the person who lives across the street from my flat. 
Well, almost.  .  .  .
I moved in at the end of September 2018 and in all that time this window is the only one to suggest continual occupancy.
When I first moved in, the larger window to the left (North) of this was occupied by a young woman who would habitually smoke a cigarette out of her window while I was mounting my bicycle to work. I don't recall when she moved out, but that window has remained unoccupied ever since.
Below that window is another identical, which was briefly occupied by someone I was told was a squatter, and all I knew about him was the frequency with which he extracted beer cans from his fridge.
To the right (South) of that is the window below this one, which has been vacant all of the time I have been here.
I have been told by the shop on the ground floor that all of the flats in this building are housing association property.
This is the same building which suffered an horrific fire last year and I understand that all tenants were urgently relocated.
And that really is everything I know.
I have my own guesswork about the inhabitant of this particular window, but I would be really interested to hear what theories you might have.
This is a purely personal experiment to investigate my own subliminal stereotype pigeonholing. A survey.

Away you go . . . Let's have it
