Megan and Richard

I don't understand, why my little Megan like to hit or slap and even pinch her cousin, Richard? Because of jealousy? Richard, as gentleman as he's never hit back, just said " mei mei, bu yau da ke ke"... aiyooo give me headache
Yesterday, she pinched him under his eye hard and left red stain, still Richard will look lovingly at her and call mei-mei.....
If we asked Richard who're the prettiest among his cousin, he'll undoubtedly replied : 'mei mei'
The problem is, Megan doesn't appreciate his passionate and keep bullying him, what must I do??????javascript:void(0)
