This is something that never occurred to me, so I just thought I'd throw it out here.
A friend (I'll call her Mary) has had a long time dream of traveling to Italy. Mary's husband has no interest in travel, but about 6 months ago another friend called to say that she was going on a trip to Italy with her church, there were extra slots on the trip, and did Mary want to go? Mary jumped at the chance and last Wednesday left on her first ever trip out of the country. Unfortunately she had a bad fall on the first day of the trip and ended up hospitalized with a badly broken leg which will require surgery.
Mary's travel companion offered to stay on with her and miss the rest of the trip, but Mary didn't want her to do that. Thankfully Mary does have trip insurance which pays for someone to fly from the U.S. to be with her but...her husband has no passport and didn't even know where his birth certificate was. He could have gotten an emergency passport but would have been delayed an extra day or two in getting there and it was possible that Mary would have surgery sooner than that. Under the circumstances, a friend offered to go instead because she had a passport and could leave on short notice, so that's what happened. Mary is scheduled for surgery tomorrow and hopefully all goes well.
