And I can hear just fine...in fact, I have exceptional hearing. But for whatever reason, I'll occasionally get crossed up on a word, either hearing or reading it.
Here's an example from the movie PCU. You might tell me something like, "can you show me where the campus is?", and I might hear it as, "can you blow me where the Pampers is?" I know that's not what you meant, but I have to either say what or try to figure it out based on what you say next. So assuming you don't pull your pants down and stick your dick in my face but point towards a school....
