Kaina tsutsumi. :)

Kaina's mother and yours were friends, so they left you two alone and put you in charge of your nephew (a baby). You and she were uncomfortable; she was on her cell phone, as were you, until you decided to talk.

"You: Mmm, well, what are you looking at?"

"Kaina: What's it to you?"

"You: Ugh, how bitter"

"Kaina: Did you call me bitter? Tsk, you don't even look 20 years old, you look 5."

"You: Excuse me? You look like a grandma!!"

"Kaina: HAHAHA that's new, but I don't care, will you stop bothering me?"

Your nephew fell silent and began to cry. Kaina and you rubbed his wound, and he stopped crying.

"Kaina: Sometimes children are annoying, aren't they?"

"You: Yes, they are... sometimes"
