You do realize that you ended your sentence with a preposition? Reminds me of an old joke.
A Texas college student went to South Padre for spring break. There were college students there from all over the country. He sat down at a bar next to another student and tried to make polite conversation.
"Howdy. I'm from Texas A & M. Where do you go to school at?" the Texan asked. "I attend Harvard, a university where students are intelligent enough to know not to end a sentence with a preposition," the other student responded.
The Aggie thought for a moment and replied, "Well pardon me. Where do you go to school at, asshole?"
Of course I realized. It is a very old joke.
