Disillusioned

a stranger comes knocking at your door,
but is he really a stranger,
or is he someone you've crossed path with,
but no longer in your memories?

a friend crosses the street,
and you stop to say hi,
he doesn't seem to recognise you,
or is he just in a hurry?

an enemy sits beside you in the lecture room,
but he doesn't seem to notice you,
he knows that you hate him,
or, does he really?

a girl looks at you from across the room,
starts smiling and waving,
but is she doing that to you,
or the person right behind?

you see what you want to see,
and you screen out those which don't fit,
sometimes we get disillusioned,
or is it just reality?
