"How are you doing, love?"So what shall I answer back?
"Yeah all good, I just had a bout of suicidal depression, due to which I felt forced to stay in the office til late. But that's nothing that two pints o' beer on an empty stomach, together with Fry and Laurie, Monty Python and Rowan Atkinson sketches can't solve"?
That wouldn't do the trick, I guess. I'll have to go for the formal, pitiful, farcical way: "all good, I've had a rough one at work, I'm calling it an early night."
