Sounds like someone needs some sensitivity training

Milo: “Mom, what if there was a guy who was really small and always said, ‘Waaah! Waaah!'”

Me: “I’d probably think he was a baby.”

Milo: “Yeah, but what if THIS guy was 300 years old? WHAT WOULD YOU DO?”

Me: “I’d probably say, ‘Hey dude, I wish you could talk because there are so many questions I want to ask you! Like, what was it like when you were only 5 years old, and what do you think about the changes you’ve seen over the years, and how did you get to be 300 years old? Can I be 300 years old?”

Milo: “And he’d say, ‘Waaah! Waaah! Waaah! Waaah! Waaah! Waaah!”

Me: “And I’d say, ‘Learn English, dude!'”

Milo: “And *I’d* say, ‘Mom, this guy is weird. Can I punch him in the head?'”
