So, I'm sitting at the back in Zac's and one of our regularish friends comes in. He can be erratic in his behaviour so the fact that he is wielding a very large trowel is slightly concerning.
He sits opposite me and explains that his dad taught him how to use a trowel when he was a boy. All the same, this is a very large trowel (of the cement spreading rather than digging kind) and, more importantly, a potential weapon.
Oh dear, should I ask him to let me look after it until the bible study has finished? He's in a good mood but that could change suddenly if he feels offended. I can't catch the eye of any of the God Squad lot to signal - although what I would signal is anybody's guess - I'd probably look as if I am doing the actions to Twinkle, Twinkle, Little Star - so I look around: is there anybody here with whom he might pick a fight? One possibly but he'd been off the drink for a few weeks and is sober and cheerful so unlikely.
Of course there's always the possibility that trowel-man's mood could change or something could be said to upset him. But on the whole I figure it'll be okay. Which just leaves the question: why is he carrying a trowel?
