At the box in front of me a young man at the end of the shopping asks:

Give me a kidney.

For a boy or for a girl?

Aha, what is the difference?

Well, for boys there can be a designer inside, or animals of all kinds. Or here dinosaurs, or wolves there are, puzzles.

And for girls?

and princesses.

I took for a boy. He left the box and handed it to his daughter.
