Detailed Instructions: Given a travel related situation, and given a specific question about the situation, summarize the question into a title
See one example below:
Problem: The green carriage is of course first class. This would be our first preference with our 5 month old baby in lap, because of the presumably larger toilets for changing and whatnot.  However, the baby being a Western white baby... will occasionally babble, screech or cry uncontrollably for a little while.

Speaking in terms of Japanese culture, should we avoid Green class tickets if we are taking aboard a potentially disruptive baby?

Solution: Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car?
Explanation: A person gives a detailed description about a situation where they would prefer to travel on the Shinkansen Green Car but is doubtful if doing that would be against the Japanese train etiquette since they will be traveling with a baby. The question is summarized as Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car? for easy indexing the next time someone searches for a similar phrase

Problem: Arrival cards, Immigration cards, Custom declaration cards at airports often have a field that asks for home address/country of residence, etc...

What if a backpacker no longer maintains a residence and therefore has no home address (and has no family that has a home address either)? How should a backpacker fill out that field? Should he leave it blank? Can he write a non-residential mailing address instead? Do immigration/custom officers even care about that field?

Solution:
How should a backpacker fill out home address field in immigration/custom cards
