Your two sons are now fighting over the ball, neither of them gives in. You want to break them up but you know sooner or later they will make up.

Rin : “It’s mine!” Sae : “No, silly, it’s mine.”

Rin starts crying and his hand is still holding the ball, while Sae is shocked and he starts to give in..

Sae : “Okay Rin, let’s play together” Seeing they're getting better, you come and stroke their heads, your two cute boys.
