Yes. Because I have that sort of a brain.

Sometimes I do and sometimes I don't. Good ol' El Nino.

Hell yes.

I know mine by heart as the letters and numbers are remembered using association with other things.

I do this for other things as well but I also have very good recall for conversations, trivia and other assorted nonsense. Sadly it doesn’t extend to numbers although I have now learnt my mobile number and can recall that.

Yep, because I filled it in so many times on job stuff.

But also because that's how my brain "works"
