Insane?

You are my best friend in the World and you tell me all kinds of important facts of life including what to do with an aubergine, how not to put "yellow" dusters in the washing machine with my regular washing and much more, so, I know you'll tell me if I'm nuts for vacuuming my mattress?  I flipped my mattress yesterday as back has been killing me, I've been meaning to do it for weeks but it's so heavy, anyway, I summoned the strength and after I'd flipped and as I was there, kneeling on it with the vacuum attachments fully loaded I did think; "hmmmm, would Col tell me I was insane?"  This is hypothetical by the way, I think I know the answer to this particular question.  You do know there will be more of this to come right?
