During sanchi ganga Jagya triangle time, they used to talk frequently and even after that for some time.
Then suddenly the interactions stopped as anandi was caught up with pleasing DB and social work and ganga was busy with both kids and a career.
I felt happy when ganga called up anandi. Sometimes we all feel lonely even if surrounded by family members. We feel the need to talk to someone who we trust.
This is the reason why penfriendhips were popular in bygone days and now facebook friendships are flourishing.
