Lamppost of the back alley

Spreading four legs
the dog sleeps as if it is dead.
Another one, at some distance
sleeps like a cue ball.
Some nights, I see some men
three, four, or five
to gather in the back alley
ignoring the rule of social distancing. 
They don't know
they are observed.
Why they sometimes lit a fire
under the lamppost
--a curious question to ask.
Have they taken a social responsibility
of burning  trash?
And if so, why don't they choose a
different lamppost each time they burn?
