Bloody Birthday!

I was in year 7 (11 years old)and my BF was throwing a party for his 12th birthday. I was so excited so I wore stone washed cut off jeans, a white blouse and cute little black pump. Everyone was saying how nice I looked! Anyway we were sitting in the cinema and all of a sudden I felt strange so I took a trip to the bathroom and yes indeed, I had started my period. To make matters worse I had no protection and blood staining my jeans. Mortified I tip toed back to the film and told my BF that I needed to go home because I really didn't feel well! HE understood so i though i should tell his mum, she understood aswell but just as my mum pulled up she called out to her 'Is everything okay?' and before i could say anything my mum called out (In the middle of a bussling town "Yea she's fine, She's just started her period!" well, I could of died right then! Mortifided isn't the word and to make matters worse I have just started work in an infant school when his mum came in, looked at me and just smiled! I thought 8 years would be enough time for her to forget!
