What am I?

I am just wearing a mask.

and underneath that, another.

I am wearing enough masks to not leave room for anything else.

I am an onion.

I am a zombie.

I am a turd with gold finish, pretending to be worth something.

I am everyone

I am no one.

If it were a few degrees warmer it would be raining.

Placebo

A placebo doesn't work If you know it's a placebo.
Though if you told me today
what you told me before,
I would still believe you.

Because unlike the starch and sugar
"Mood Enhancers"
In the purple bottle
on the windowsill,

I just keep hoping
that one day
you won't give me a placebo.
