A painter’s patience (my first joke)

A painter asked his client where to start painting his house.

-“Roof” said the client.

-“Ok” said the painter.

Moments later after hard work, the painter went back to ask where to proceed painting.

-“Where now?” Said the painter.

-“Roof!” Yelled the client.

-“I already painted there, tell me where to paint now…” Said the painter with little patience.

-“Roof!!” Yelled the client again

With anger in his eyes the painter said:

-“That’s it! This is the last time i paint a dog’s house!”

I hope you have a stupid smile because of this stupid joke.
