Growing up as a youth, there was this elderly Man in our neighborhood that I will represent here as "Grandpa”. He was exactly a Grandpa, though not very old.
Grandpa was married and his wife was still alive, strong and healthy, though, she was always on and off, hardly around. She was always on the go, visiting their children on regular basis, based on their invitations. They loved their father so much, at least in their own wisdom, and were always ready to do anything that will make him happy. However, they hardly invited him, and hardly visited him. Whenever Grandma travelled, she stayed long, at times for upwards of 9 months, and after a stint with Grandpa, she embarked on another visit. In one of such numerous visits, she stayed away for two years plus.
