After our guests checked-out I was cleaning the guest rooms. And then my son came and said,

"What can I do today?"

When I clean the guest room my son usually comes and says so, because he doesn’t go to pre-school on weekend and he has a lot of time.

"OK, could you help me to clean the bath?" I said.

.      

    .

I taught him how to clean the bath tub and he started to do it.

Wao, he can do it very well!

"OK, let’s start to clean the next room, Yuuki."

But he got tired this time and started to play with bubbles like this photo.

However I think, he is a good helper for me though he is still 4 years old.
