I Got "Ang Pow" Before CNY

Yesterday i splash water on my friend but missed.
Means, the floor is wet.
So i went off and take all my notes and things from locker.
Then i noticed that i left my water bottle in another class.
I run quickly and when i reach that wet floor.
I step on the water and i felt.
Luckily that is no one there, how shame i am.
My leg still pain.
My friend all laughed at me when they knew about this.
