First Impressions

I can only imagine the assignments we'll be set on the first day:
"First Impressions"
Pick a person in the room and write.
So I'd pick up my pen and look around,
Pretending I don't already know it's you.
You caught my eye as soon as I walked in,
For all the wrong reasons of course,
But I can't seem to stop looking.
Maybe I'm trying to find something good,
Or maybe I already did and I'm trying to convince myself I was wrong;
It was a trick of the light,
Something in my eye. 
Description, that's what I need,
But you're too far away to see your eyes,
I might never know what shade
Of sea-glass green or sky blue or chocolate brown 
They are. 
Chocolate, that reminds me I have a snack in my bag...
Isn't it strange how thoughts do that,
You have one and it sparks a hundred-thousand others,
They dance around in your head,
Like motes of dust in afternoon sun,
Until you pick one to use. 
Now I'm thinking of dust motes,
But in early morning sun this time,
Peeking through a gap in the blinds of my bedroom
Come to rest on the curve of your back,
Where my sheets are pushed to one side.
