I'm trying to teach myself Russian at the moment, and was looking on Amazon for a book to help me practise the very complicated grammar. I found one that looked ideal, but then noticed that one of the sentences in it referred to " ... the boss'es car ..."!
Surprisingly (or foolishly?), I have still gone ahead and bought it, telling myself that as the author is Russian, the mistake is perhaps excusable, and that hopefully his Russian is perfect.
That's not like me - as I think I have mentioned elsewhere, DH and I have been known to walk around for hours looking for a cafe that doesn't claim to sell "sandwiche's", "lunch box'es to take out", and "tea's".
Glad to know that I'm not alone in posting things with grammatical typos in them though. Someone once sent me a PM to tell me I'd just put an apostrophe in the possessive "its". How embarrassing!
Fortunately, it was a site where it is possible to edit posts.
