I Can't Read or Write

I didn't get much schooling so I can't read or write.
Many people don't understand my situation and plight.
I thought I was buying sugar but I bought salt.
My cake made people puke and it was my fault.
When I drive, I can't read stop signs so I always crash.
Over thirty people have sued because of whiplash.
When I was seven, Dad wouldn't let me go to school anymore.
When a person can't read or write, it closes so many doors.
I can count to ten but I have to use my fingers and thumbs.
And if you actually believe I can't read or write after reading this poem, you are dumb.
