And not in a good way before you get all excited and can't wait to read on. In a very, very bad and disgusting way, I shall explain and I shall be brief for those of you wanting to go elsewhere for your kicks.
I was fasting and had only had water for two days when I went on a charity volunteers training course. I walked into the session at 9.30am and refused the proffered cup of tea and ignored completely the smell of the warm fruit scones that other people were slathering with butter and strawberry jam. I quickly went into the main room and sat down sipping water from a bottle and listening to my stomach growl as some bitch sat next to me with butter dripping from her chin. And had she not been in her early 70s and very whiskered the temptation to lick it off may have proved impossible to ignore!
Anyway I got through hours of lecture and group exercises before being told we should order lunch. I told the trainer that I was fasting and wouldn't be eating lunch. She looked at me as if I had grown two heads and passed the order onto someone else.

We went to the local pub for lunch. I sat opposite this fella who ate his lunch while I began to drink a glass of iced water with lemon - quite nice actually and I was womanfully ignoring the smell from his battered sausage - ooh err Mrs!
we were chatting and he had this terrible habit of spitting when he spoke. I sat horrified as some of this spittle along with, I swear, a chewed bit of chip flew into my drink. FUCK! I couldn't eat, the water jug was empty and I had to sit for another 20 minutes watching him chew with his mouth ever so slightly open - and no the idea of french kissing him to get some chips was not anywhere near on my slightly deranged mind.

Back at the training centre I treated everyone to the very loud protestations from my stomach until we wrapped up at 3pm.

The moral of this story is, if you are going to fast, do it when you can lock yourself in the house and ignore the world at large. Oh and don't bother speaking to people that have a terrible spitting habit.
