This is SuperSpouse's Challenging Evening
His transport society is getting a visiting speaker, who'll be using a laptop and data-projector. Yesterday, SuperSpouse bought the data-projector and some speakers, and we connected it all up to my laptop. It worked.
If it all works with his fellow enthusiast's laptop tonight, he'll be jubilant.
I ought to be building a WW2-style bomb shelter out in the garden, so I can take cover if it doesn't. No reason why it shouldn't work just like it did last night, but we don't know about the other guy's laptop! What if...? No, don't even go there.
If you read this, pray. Pray long, hard and sincerely. And it will 'be all right on the night', I guess!
