Crankiness

I  thought she was cranky, but found out instead
that the glasses she wore were too tight on her head.
I thought her cantankerous, but then I  found out
that she lived in confusion and crippling self-doubt.
I thought she was moody and viscious and cruel,

when actually someone put a tack on her stool.
There's always a reason for having the blues.
I thought she was cranky but found out it's her shoes.
