Sign Function

The door said “Push”
So I pushed on it
But it wouldn’t budge
Not even a bit

I scratched my head
And tried again
With a result the same
So then

I changed it up
And tried to pull
But the action once again
Was null

I was a most
Frustrated guy
Until a message
Caught my eye

I guess I shouldn’t
Have ignored
The bigger sign
“Use Other Door”
