Am I Invisible?- seriously revised

This poem practically does not look the same as it originally did and I think, it serves its purpose a lot better now.

Am I Invisible?

an ant in the grass, a cloud in the sky?

Do I blend into the background,

a chameleon lost on a branch?

a used car with 100,000 miles, a rented textbook?

Am I an object to pass around,

a broken chair tossed onto the road?

an old rusted penny, a nail dropped from a table?

Am I here to be stepped on and forgotten,

an unraveling rug sitting in the basement?

a key on a chain heavy with silver, a dropped diamond?

Have I been lost in the sea of people,

a two of spades in a deck of ripped cards?

a bright red raincoat, a polka dotted purse.

I refuse to be invisible,

the siren from an ambulance.
