Invisable

sat there,
everyday,
always there,
always listening,
always watching,
hearing the chatter of class mates around you,
always listening,
always watching,
you see them but they don't see you,
your just that empty, spare seat in a class room,
bit of air,
then poof some one speaks,
to you,
asking something,
you take a moment to digest what they have asked,
but, oh wait,
you go again,
left there,
in that empty seat.
