[Ah... yes, this certainly is strange. Natsuru gives an awkward, nervous little chuckle at Naoto's attempt to fill the silence.]

Aha... I was just thinking you seem shorter...

[This is not a normal topic to be discussing at all. She's blushing more and more, remembering how much she'd admired the cool adult Naoto when she was small like that. Now that she's back to normal and over a head taller than the other girl, everything seems so different.]
