I came in to work today to find this letter on my desk. It reads:

Dear Sir,

Re. Which? 2011, June, 38

Sorry, but I am not going to allow you to get away with it:

“bacteria” is NOT a singular noun!

I ask your organisation yet again. Why perpetuate ignorance? After all, you have so many “experts”!

Please do not reply , if your intention is to defend the indefensible.

Yours faithfully,

[a reader]

I plan to write many, many letters like this when I retire. Watch out everyone.
