why does smoke follows you around a fire

WHY DOES SMOKE FOLLOW YOU AROUND A FIRE

wikipedia.org
have you ever sat around a campfire then the smoke seems to just head your way
so
you move around to the other side then it moves back towards you
like
its got a mind of its own
or
it has something against you
or
its out to get you

there is a scientific explanation why
lets see if i can explain it
if you read this and still dont understand it 
then read this nice article explaining the science behind this

basically when you sit down around a campfire you displace the airspace you are now occupying
there is sort of an air vacuum thats formed which pulls the smoke towards you

if for example you sit across the campfire from a group bunched together
the campfire smoke will head over towards them instead of you
try that at your next camp out to get back at your other campers

if you all sit equally spaced around the campfire it goes straight up 
unless of course
there is a strong prevailing wind

again 
if you dont understand how this all work then read the article

now
i just need to find a campfire somewhere to try this out

that sure explains how the smoke always got in my face when i went to toast marshmallows in the campfire
