Grandparent Guilt

The guilt you feel when you have not visited your grandparents in a while. Intensified by the fact that when they inevitability die of old age, you don't want to feel like you didn't see them enough while they where alive.

Mum: "When was the last time you saw your grandparents, they won't be around forever you know"
You: "Stop giving me grandparent guilt, I will go see them soon."
