You're doing it all wrong
You need a holiday on Thursday where you stuff yourself to the gills, watch some football – your kind or ours, it doesn't matter.
Then you'll wake up Friday morning full of energy for shopping.
(And to the nutters that insist on calling us USAians – you know who you are – just stop it. You know the proper word. Just try telling a Canadian that he's an American too and see how far Canadian politeness really goes.)
