I have a chip out of one of my front lower teeth.
The missing chip is my young sister's chin
To explain...
As was normal in the days of innocence in the mid-1960s, all the weans in our short street - so about 500 of us - were playing a street game we called 'ra-leeze', to give it its phonetic pronunciation. The game was played until we were called in once it got dark.
It was a version of hide and seek. Some poor sod was 'het' (ie 'it') and their unenviable task was to find the others who were hiding locally. The idea was to 'release' the ones 'het' had managed to find. The lamp-post opposite the house in which Kevin Bridges grew up - his grandparents' house which his mother inherited - was the 'den'.
When 'het' spotted one of us they called out the name and ran to touch the den before the person who'd been found could do likewise. That made the found person a prisoner in the [imaginary] den.
On this occasion my wee sis was 'het' and she had a few in the den and I took it upon myself to try and release them. When I notice sis far enough away from the den I made a bolt for it. Not the locking type of bolt - more the Usain type.
She saw me make my move and we both ran full pelt towards the den. This was nothing unusual and usually the people involved in a close-run event went either side of the lamp-post in order to avoid a collision. On this occasion, both sis and I misread the other's run and we both touched the lamp-post at about the same time but ran straight into each other.
My mouth hit her chin. I have the chipped tooth and she still bears the small scar of where my gnashers smashed into her chin.
Fortunately we can still laugh about it.
