I had to leave the canteen in the middle of my sandwiches and go for a little walk to the end of the industrial estate and back.
I mean, WTF? What is wrong with me? What is the big huge personality defect that means I fall again and again at the final hurdle? Do I smell? Am I boring? Am I a bit peculiar? Will somebody please tell me so I can work on it?
A fresh batch of application forms arrived in the same post, and so the cycle begins anew.
Every time I think I've reached the absolute end of my tether, I find there's still plenty of chain to yank.
