Loosing? Learn the English language, people!

I don't know about laziness--that's probably a factor in some cases, but most people who make that mistake simply don't understand the rules for apostrophes (let alone other, more basic rules about singular and plural, for instance).

You could argue (though I'm not suggesting they have the same implications when not adhered to) that much like the highway code, not understanding is no excuse. "Have you considered grammar training!" ;)

Of course we all makes mistakes, and I for one frequently look up the spelling of words to double check them. I think what offends me most is when people who 'should know better' make these basic errors. I'm working in a school at the moment and it's startling how many of the teachers and administration staff struggle to write correctly.

I suspect auto-correction on our computers and smartphones is making people lazy.
