Did the teacher mean literal words?
Literal interpretation of language means people interpret literally what you mean.
For example, if someone said, "Pull up your socks", a literal interpretation would be pulling your socks up. Whereas the interpretation most people would make is: work harder, apply yourself
I hope that makes sense.
I know one day I was cross at one of my sons withs Asperger's. He was taking forever to get dressed for school and I was frustrated. I yelled at him, "Pull your finger out and go and get dressed!". He innocently looked at me and said, "Pull my finger out from where? It's not stuck anywhere!"
