Don't use "u's" where "u's" have been eliminated in the U.S. even though U were taught to use "u's" when U were in your favourite school or we will question your behaviour.
Don't stop in the middle of a store aisle to visit on your cell phone, oblivious to the other shoppers who could care less about your conversation!!! @#$%^
Don't forget to record every single episode, in case you get interrupted, so you will not miss anything.
(OR perhaps recording one a month would be sufficient, for you to know what's happening. )
