It’s okay to end a sentence with a preposition

“My mother always told me I shouldn’t end a sentence with a preposition.”

I don’t agree with that client’s mother. 

It is okay to end a sentence with a preposition. At least, it’s okay most of the time. Because, as Grammar Girl says, it doesn’t sound natural to say things like “On what did you step?” instead of “What did you step on?”
