sometimes hals (angela's ) answers and reasons are right on the mark . here is a small example when i talked about not hogging all the hot water in the shower , hals answer was info as to what happens when thats done and what comes out (cold water ) .
Lonnie: don't hog all the hot water in the shower ha !
Angelaredhead: Ha yeah and then the hot water stops in the shower and cold water comes out!
Lonnie: yeah and thats cold !
Angelaredhead: Yeah and that's what makes it so cold!
Lonnie: yep
