IPhone for Orphan

Listen up, buttercup. The joke is that the iPhone XR doesn't have a home button. Get it? An orphan doesn't have a "home" either, so it's like a sad, messed-up wordplay. The author is trying to be funny by linking the kid without parents to a phone without a home button. And you, my friend, are as sharp as a marble, so I had to spell it out for ya.
