So I noticed that when I put on my tail, you can still kind of see my knees. I'm sure that I'm not alone with this, so I came up with an explanation for it for kids. I say "Well, since I'm a half mermaid, I'm really still human up until my knees, but I still have scales. So I still kinda of have knees, but they're not very visible." Or, "What are knees?" and once they explain knees to you, you could say "Well, I certainly don't have those. This is just my tail joint."

So, what do you think? Do you have an explanation for knees that you tell kids?
