Isn't it more fun?

Just plop a whole grape into your mouth, skins and all, and take off the skin while it's in there.

You can't be lazy like that.

You should peel the skins off properly before eating them, nanodesu.

Oh my, are you two having a fight? Just what are you arguing over...

Ah, Kashima-san! Do you eat them unpeeled?

Hmm, right... well, you could fit one in your mouth without peeling back the skin, but leaving it covered can be unhygienic,

so you should peel the skin first before inserting it into your mouth, yes.

Ah, but peeling the skin with your mouth is quite the high-scoring achievement.
