Whilst trawling through various journals, I have noticed that a lot of people make the same mistake.
- Wrong: The other day this bloke stepped right on my foot. He should of been watching where he was going.
- Correct: The other day this bloke stepped right on my foot. He should have been watching where he was going.
The thing is, it's such an easy mistake to make... because that's what it sounds like!
Most people abbreviate "should have" and "might have" to "should've" and "might've"... which sounds almost exactly like "should of" and "might of".
Through a lack of anything else interesting to post about, this is what I'm reduced to... picking holes in grammar!
