Given a travel related situation, and given a specific question about the situation, summarize the question into a title
One example: 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 is here: 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

Now, solve this: I received my Iranian visa two days ago. My plan was to go there for a week, but unexpectedly I have an extra week available (due to an event in Turkey being cancelled just recently). Therefore I would like to extend my stay in Iran - to be precise enter the country before the date I put in my application. The itinerary would change a bit too.

Is this a problem? According to the date printed on it, my visa is valid for the entire period. Do I have to notify the embassy or the Police Department of Foreign Affairs or the party, I got my invitation from, about these changes?

What is the best way to handle the situation? I don't want to run into any problems, but I also don't want to miss the chance of spending some extra days there.

Solution:
Travel changes with an Iranian visa
