Actually, what he wanted to say was, "It's just a kiss, what's there to be so proud of?"
Alright, he wasn't able to express himself that way and could only bluntly say, "Brother dumb."
When Yang Chuxia heard this, she turned around and hugged him, "You little rascal, you mustn't call your brother dumb, okay? Brother is very smart."
But Lele wouldn't give face and still shouted, "Brother dumb!"
Yangyang, nestled in Ms. Wang's arms, naturally also heard his brother's words. Although he couldn't say three words together, he knew this wasn't anything nice and pointed his finger towards Lele, then yelled, "Dumb, dumb!"
The implication was clear, "You're dumb, you're dumb!"
So, all the way there, the two kids kept squabbling over who was dumb.
However, during normal times, everyone would have stopped to tease these cute babies, but at this point in time, everyone's hearts were heavy, and they didn't have the mood to tease the children.
