Oh dear, we can all forgive a little slip now and again, but to make this most heinous of all grammatical ablutions on a wall art site with the effect of repeating the offence over and over again in people's living rooms around the country? Totally unforgivable.
I've just noticed it's not their only crime either, this one (also on the front page) has no less than three missing apostrophes:
Is it bad of me that, when talking to an interested party on a dating site, I stopped messaging after she used the word "car's" as a plural?It's not bad to decide you're not going to marry her but only a fool chooses to throw away a possible shag because she doesn't know where to use apostrophes.
It's not like moans of low-to-medium pleasure sound different with misplaced punctuation.
