I feel nothing for my grandpa
I am sorry to hear that. Why do you feel nothing for your grandpa?
None of his family cares or visits him except me and my dad. He never says thanks.
You really need to care more about your grandpa. He probably loves you, but can't show it. Try to get along.
Can't people just chill?
Usually people make an effort to show care for family. In the long run it is important to support each other in life.
