I flew into Sydney recently, around the time the Pope was leaving after World Youth Day. I figured if I saw him, I could go and stand near him and sneeze. (Don't ask me how I'd make myself sneeze – I hadn't worked out that part of the plan.)
Hopefully, he'd reply in the standard way, and I'd have a great story about getting a blessing from the Pope. But then I thought – hang on, the current bloke is German. He'd probably say "Gesundheit" instead, which doesn't have the same ring to it. I'd be stood there, complaining at the Pope, telling him that he should've said "Bless You" instead of "Gesundheit". At least right up until I got carried away by his security.
I'm also thinking that I missed out on a great opportunity in a lift earlier in the year. I must remember to have the sniffles next time I bump into one of the great religious leaders of our time in an enclosed space.
