In a post containing a lot of links and insightful details, Sujatha writes about the recrudescence of people wanting to return to India, and the life of migrating families due to jobs or otherwise:

 Within a few weeks, my mom would be fully involved in her neighborhood and my dad would acquire a gazillion “walking friends”. I never heard my parents complain about having to start over every two years or having to move away from their siblings. Rather, there was an air of excitement. This taught us nothing if not resilience and the idea that when faced with a situation, you put your head down and did what needed to be done and moved on.
