We used to play four squares in the street that I lived growing up. Chalked onto the pavement the big square then it was divided into four smaller squares. Four of us could play at a time letting the ball bounce once then hitting it into another square until someone was declared the winner or somehow it had gone over the hedge of the neighbour's garden. And it was me they pushed forward to retrieve the ball, being the youngest and very shy, 'Please Mrs Ellis can I have my ball back?' Otherwise, it would end up in the bin, sliced in two. (Maybe i'm still traumatised, a childhood memory I won't forget)
