There were at least 10 people and 4 boys be volunteers.

It started from 12:20 to 5:30pm. In fact, I didn't help much at all.

So I standed most of time and watched them to build a new side walk.

haha, u r more like a supervisor工頭 to them

Yesterday one guy who volunteered was making fun of me by telling the same thing as you said.

We met the guy when we were waiting for the parade
