Option...well, 4.5 maybe...
I'd like to be a teacher, but I can't see I'd be any good at it. I'm appalling at discipline. I'd be that supply teacher that you hate having cover your class because little to no work gets done and the room's a tip.
However, my Fiancee's a newly qualified teacher (and both my parents are/were too) so we're not neglecting the education profession...
