I had a bad stomach cramp last Friday after lunch. That was my first day of PMS. On normal basis, the pain will increase, it excruciating and unbearable. On that particular day, i was like "yay! Tomorrow is Saturday. Finally it's weekend! Hell cares whether I have cramps or not?". The thought of not having to work, made the pain easier. If it wasn't for Friday, I guess things will turn out different!
P/S : Come to think of it, it might be Shikamaru who made the unpleasant pain go away *day dreaming*
