whistling

Teacher gets mad with our laziness sometimes

I don't understand what's happening

We're about to work, not to sit on the bench

Talking about behaviour to the kids

Sometimes it's hard to get through to these youngsters

Seems like teacher is not contented at all

Trying to self escape from teacher's commands

Teacher is not only a friend but also a demanding mentor

You know, i doesn't care

You should do as you was told to

A little whistle concert in your honor, boss
