Di-di's feeling happy... and kind of smug these few days.
That's probably because he had just learnt how to stand on his 2 chubby legs, while grabbing onto something for support of course.
But he can't tahan standing for too long yet, so he'll always come tumbling down soon after. Hee hee...
Sometimes I'll be the nice kor-kor and hold his hand while he's standing up. But no use lah; I'll always end up tumbling down together with him too.
