The simple reality, which I know you understand but are pretending not to for whatever reason, is that when you're the size of this kid, normal everyday tasks are just more challenging. Obviously, I know you understand that trying to find a size 23 shoe, which is the largest Under Armor has ever heard of and requires 3D foot scans and custom-made shoes, is a considerably more challenging task than buying shoes for 5 normal-sized kids. Again, I know you understand that. But this obviously goes beyond shoes. Shoot, the kid is just 14 and already 2" longer than a king size bed. A king size bed is what most people aspire to for relaxation and comfort. For this kid, it's an absolute bare minimum at the age of 14. If he grows 3 more inches, he'll exceed the length of any standard bed size. Again, if you're Shaq, you can get a custom-size mattress no problem. He'll most likely have to sleep diagonally in bed for the rest of his life as an adult. Even now, sleeping diagonally, his height requires a minimum of a queen mattress. Is that a tragedy? No, of course, not. Just an illustration that everyday simple things us normal size folks don't think twice about require special consideration for folks who are this size. If someone told you "for the rest of your life you have to sleep in a bed that so small you'll have to sleep diagonally just to fit" you'd think at a minimum "well, that's kind of inconvenient." And if you ever wanted to get married..."well, hon, I hope you're ok with me having to sleep diagonally in the middle of the bed for the rest of our lives."
Don't be intentionally obtuse.
