Kids keep telling me my boobs are big.

Well duh!

'Course they'd say that...

Take never says that though...

So you want him to tell you that...?

How can I get him to say it?

Take! It's really big, isn't it? In the Japanese it is ambiguous as to whether they are referring to her breasts or the watermelon, but plurals make it clear in English.

...Yeah, it is.

Wait, I only got him to say the watermelon is big though...?

No way! They're bigger than the watermelon...

Kobayashi's Idea

He's probably interested, but he tries to be a gentleman about it. That's pretty decent of him...
