Why didn’t the man attend the picnic?

W: I didn’t see you at the company picnic last weekend. You had such a good time at the last one, so I was surprised when you didn’t show up for this one.
M: I had planned to go, but when I got up in the morning, it looked like it was going to rain, so I decided to stay home instead.
W: It looked like rain? Are you sure about that? It was sunny all day long at the picnic site.
M: When I woke up in the morning, it was really cloudy and overcast, so I just went back to bed. I suppose that the weather cleared up later on in the day.
