Rei Qi and Yi Han are really quite the sisters act.. Yi Han has the strongest grip and yank on hair and Rei Qi's flailing hands pack quite a punch. Yet when we put these two girls side-by-side on the sofa this morning, Rei Qi excitedly waved her hands all over the place but slowed down so that she will not hit Yi Han. And Yi Han smiled directly at Rei Qi, grabbed a handful of her hair but did not yank and actually just let go. The two just smiled and laughed at each other like the best of friends. Makes me so happy...
