Here's a conversation that's happened several times (almost verbatim) with me today:
[Me] That's / this will be the second time I've matriculated here
[Them] When was last time?
[Me] 2000, when I was going my PGCE
[Them] But you shouldn't (have to) matriculate twice
[Me] Yeah, I know. But I couldn't be bothered arguing
Oh, and today doesn't feel like a day off (because of aforementioned matriculation, and some Greek learning that I might as well do while I'm in a work-related frame of mind).
