I can relate to the the comment about the missionaries...

In April 2005, I flew from Hong Kong to Jakarta and sat across the aisle from two members of the Church of Jesus Christ of Latter Day Saints. They tried to con me into their game, but I argued with them, thus making the flight go faster.

On my way back a few days later, I sat next to, in fact a member of the same church, but this one was telling me about how he helped out Vietnamese refugees make do in Hong Kong after that conflict had ended in 1975. Now, I understand that the employer of these people is not the weird part of this story, but the fact that I sat next to missionaries on each leg was a little more amusing.

also, in 2001, I sat next to an older woman on a flight from Los Angeles to Pittsburgh who hit me with her cane each time I got up.
