When my niece was first learning her age at 2, my brother and I as the evil uncles we are would ask her how old she was, at the time she couldn't distinguish between 'to, too, and two.'
She'd always respond, "I'm two!" and we'd respond, "Yeah'ar too."
As you can imagine, we couldn't just let it go because it was too adorable, so when she turned three we'd ask her.
Us: How old are you?
Her: I'm three!
Us: Yeah'ar too!
Her: NO! I'M THREE!
She figured it out eventually, but would still humor us.
Couple other gems:
- I have a friend who is a Marine and he lost his eye, she once asked him if he was a pirate.
- She used to pet my head and say, "I like your hair" like I was a dog or something.
