There goes civilisation...

I misunderstood what you meant by "buffer against redundancy", I understand now. In that case, yes, I do have one. Am I supposed to feel bad about that?

The ass-kicking I was referring to was in academic terms only. I'm not going to apologize for being good at academics. Don't worry, I'm sure you could kick my ass when it comes to riding a bike.

I only mentioned "council estates" to indicate that I don't live in some secret heretofore-unknown posh bit of Whitechapel that nobody knows about.

^ So confrontational.
Not everyone's against you. Grab your vice of choice and chill.
