Nutty - if there's someone permanent who can do the job, why are you doing it at the moment? Surely the very fact that you are there and doing the job perfectly well right now makes you a shoo-in.
Exhausted after yesterday. Got home from work at 5.20, did a quick snack for kids and back out to Welsh for 6pm. Finally got to eat my lunch at 7.30pm. Didn't bother with dinner, straight to bed as soon as Welsh ended at 9pm. Mondays kill me at the moment. The Welsh course is really good, but three hours on a Monday night? Mae e'n ofnadwy.
