When I was in year 10, I used to babysit my two brothers for my mum so she could work overtime and as payment, got 10 cigarettes a week. This worked fairly well and I babysat for months.
One day however, it went wrong. Mum had bought the cigarettes for me as usual and had sat on the sofa in the living room behind me and started peeling vegetables for tea.
At this point she decided to snatch the cigarettes from me for a laugh while taking a break from peeling. I was trying to snatch them back and she was trying to stop me and we were both giggling madly. We both forgot that she still had the vegetable knife in her hand though and as I reached for the cigarettes, she tried to push my hand away....with the hand she was holding the knife in.
Mum went white, I howled and I swear I've never seen her move that fast either before or since. Needless to say, she hit the first aid kit at light speed and soon enough, I had a rather oversized plaster on my arm for what was, in reality, only a small cut. I didn't mind though because I got loads of ice-cream that night as an apology.
Next day I was at school and it was P.E and inevitably, the teacher saw the plaster and asked what happened to get it.
Without thinking I replied, "I tried to get the cigs off mum and she stabbed me."
As the teacher turned purple I realised what I'd said and tried to explain but it was a little late by then and social services were called. It was all straightened out in the end but I've never let her live it down and still win arguments by saying, "you may have done that but you stabbed me so I win"
Needless to say, I never babysat for my brothers again
