I just made an unsuccessful search of the Internet for instructions of how to replace the cap on a tube of toothpaste. I've tried telling my son to do it, but he never does, so I figured maybe he doesn't know how. I was hoping a helpful chart with pictorial diagrams posted in the bathroom might help, but I can't find one.
He's 34.
Does anyone know where such a chart could be found? Is there a book on toothpaste use for dummies?
