The water can

This water can is these days my favourite. I take it in the house and walk around with it. Not with water, unfortunately. But outside I have my bicycle - can't reach the pedals yet - with a tray of water at the rear.

Then I decide to walk down the stairs. But I am someone who thinks before he does. Shall I walk down or would that make me fall? I decide I better be careful and go on hands and knees.
