If not now...
You can hardly trust full grown adults to give a shit what they do to your equipment. I was at a friends house playing pool. It was a mix of mostly non pool players there unfortunately. I left my cue unattended for a few minutes and when I went looking for it where did I find it? On the floor being used as the throwing line for the dart board... I really wanted to punch some faces that night.
Those would be the former kids who were NOT allowed to use their Dads' pool tables.
How can a child ever learn if given no chance to learn? He'll grow up an idiot who uses good cues as dart lines.
