In many countries where toilet paper is not used the left hand was used for the cleaning. The finger nail was used to 'scoop' the remains! I supposed it could then be used to pick you nose and then a coke spoon. 3 in one accesory
At least that is my theory. The next SWMBO has lessons with those kids I'll get her to ask them. I hope it's not the coke spoon theory, better be the status ones. Sad git, get them a nail clipper.
