Get your apostrophes right

It’s never the wrong time to get apostrophes right.

Apostrophes are the difference between a supermarket that knows its shit and one that knows it's shit; between feeling you're nuts and feeling your nuts; between "Hell mend them" (an old-fashioned curse) and "He'll mend them" (a bloke's coming round to fix your tiles).

If you can't use an apostrophe, you don't know your shit.
