I was sitting with my 4 years old student at the lunch table.  She was waiting for her ballet class in an hour time.  We were eating and chatting with few other teachers as well.

There was a small pail on the table.  She asked me what is the pail for.  I told her, “I need to wipe the environment to keep the class clean for you.”.

“Since you are free later, you are going to help me wipe the table, shelves and everything in the class.”  I said jokingly.

She replied, “HA HA!”.

The teachers are looking at her.  “What does HAHA mean?”, I asked.

“Ha ha means I’m not wiping!”  she said loudly with a grin on her face.

Her answer made us all laugh and forgot about the hard day we have had!
