Galore has a lie-in.

We had some rain yesterday evening.Usually Galore heads out of her daytime resting place just after sunset but last night she did not move, perhaps because of the noise of the rain on the tin roof.At about 8.30 I noticed on the radar that the rain would soon pass over us and stop and just about that time too we heard Galore on the move.

It was still raining as she headed out but stopped soon afterwards.How did she know that it was going to stop?
