Quarrel in the middle of the wooden bridge

One day, the little sheep had to go to the grandmother's house. Just walked to the side of the wooden bridge, and another little sheep just crossed the bridge. When they both walked to the middle of the wooden bridge, there was a quarrel in the middle of the bridge. Everyone wants to go first, and the two don’t give each other. They quarreled and screamed. Just listen to the "咔嚓" and the bridge is broken. The two lambs also fell into the river instantly.

Therefore, everyone must be modest to each other, not just thinking of themselves.
