Having just written the examination for my first year Contracts I students, thoughts of contracts avoidable by minors comes to mind. My little boys would hardly part with their toys to share with each other (being just 1 and 3), let alone to sell to a stranger. And, does a child that becomes a little entrepreneur selling a whole host of toys on Ebay make them a merchant for purposes of UCC 2-314? Let's hope not.
Thankfully for my students, its too late for me to wrap this one into the examination.
