Is it going to rain this evening?
Betty's windscreen wipers don't work in the rain. Well, they don't work in the dry either but that's a bit less bothersome.
Shall I take Betty to Zac's and hope it doesn't rain? Or shall I move Betty round the front, get Alfie out of the garage (and that involves opening the garage door, and that's a half-hour job in itself), take Alfie and then go through the reverse procedure when I get home?
Not really a choice is it?
I'll take Betty and pray hard.
