Input: Text: mandatory this didnt happen today, but two years ago. me and my friend used to throw waterballons at cars in our less mature days, we would position ourself at a junction in our village (no more than 10 cars passed a day at most) and would wait for our prey. it was a really warm summer day and all cars had their window open. now our usual tactic was my friend would spot the car i would pop out of the hedge run towards the car throw the balloon and run away again. on this day the target was a gold toyota driven by a young couple, to my dismay the front windows were closed but then i saw the back windows were open. i popped out of the hedge sprinted towards the car and as i was throwing the balloon realised there was a grandmother sitting in the back seat, the motion of my arm made her believe i was waving, oh how wrong she was it was too late the water balloon had already left my hand and the expression on her face quickly changed from joy to fear. the family spent the rest of the day driving around the village looking for us all the while me and my friend stayed in the bush before we ran home under the cover of darkness
