This is typical Darvy. It was raining and he said he wanted a drink of rain water. He thought it should taste better than out of the tap.
I thought it would be a good experiment for him so I made sure he was fully armed with raincoat and his favorite cup. And there he stood, just like that, checking his cup from time to time to see if he collected enough to drink. After at least 15 minutes he decided he had enough water to quench is thirst. According to Darvy, rain water tastes sweeter than out of the tap. ( just between you and me .... he had little more than a swallows worth :-))
