Based on the given context, craft a common-sense question, especially those that are LONG, INTERESTING, and COMPLEX. The goal is to write questions that are easy for humans and hard for AI machines! To create such questions, here are some suggestions: A. What may (or may not) be the plausible reason for an event? B. What may (or may not) happen before (or after, or during) an event? C. What may (or may not) be a plausible fact about someone (or something)? D. What may (or may not) happen if an event happens (or did not happen)? You can also create other types of questions. DO NOT make your question answerable without looking at the context, or question of which the correct answer can be directly extracted from the context. DO NOT ask a question that requires very specialized knowledge that is not common sense. DO NOT ask too simple or too short questions. Your question must be related to the context and answerable with common sense. Try to add more variations and complexity to the questions.

Context: Classy ! I believe wondering when your good deed is going to pay off is pretty much the opposite of doing a good deed . Anyway , despite that ridiculous thought , there have been plenty of times that some complete stranger did something nice for me -- many more times than I ' ve done the same in return . After college , in Cambridge , Massachusetts , I had just finished the Radcliffe Publishing Course and was hauling my suitcase to the T station to get to the airport . That shit was heavy .
What may be the reason that a stranger helped me ?

Context: It was only 60 degrees outside . The kids froze at swim lessons ! Then we came home , changed , then went to the park for lunch . It was so cold , the kids were begging to leave .
What happened after we left the park ?

Context: Ingo told us before that his apartment was in the shady part of Berlin , but it really was not what I was expecting ( probably because I ' ve seen the shady part of San Bernardino , hehe . ) It 's in the eastern part of Berlin , so what we gathered was that when it was occupied by Russia after WWII , it was n't as prosperous as the west side and thus the area is less prosperous and nice . I like it because the food was really cheap and delicious .

How was the shady part of Berlin ?
