Bad timing
Anyone who is close to their parents knows that when one of them dies, it can really hurt for a very long time. Your parents were there with you since day one and raised you to be the person you are today. In many ways, we basically owe them everything and it can hurt to lose them.
But when that moment happens, you need some support from other people around you, not just family members, but friends as well. We guess that this person just could not take all the sadness and had to walk away from it all. It’s a little selfish if you ask us about it.
