Close encounters

can't help it..
Sometimes I find
myself picturing
a guy..
in the throws of
ecstacy..
two inches from my
nose..
Maybe, they wonder why
I smile unconsciously,
on that random note,
when the vision is
coming into perspective..
It backfired horrendously
whilst I was talking to
a lad recently, who's elderly
relative I know personally,
he was the spitting
image of his grandad,
Oh no, oh no..I don't
want that vision in 
my head....
But too late..hard to hold
back once it's started.
carefull what you imagine
I feel violated..
