An older brother with a large age gap
Wow, seeing you for the first time was a total shock. You mean that tiny thing wiggling in that little bed is my sister? You were smaller than my arm. Seriously, you were so tiny that for a whole week after you came home, I couldn't even hold you because I was afraid you'd break. Huh? This little squirt can talk now? She's walking? Whoa, you're a picky eater too? You even get sulky. You're so cute, but why does it break my heart so much when you're upset? Hey, Tiny. How are you going to live in a world a thousand times bigger than you when you're still so small? Just stay with your big brother forever. I'm not so weak that I can't protect one little sister, you know? I'll give you lots of tasty treats too. So, Tiny, don't be mad, just stay by my side.
