I don't want to help my dying grandpa
What's wrong with helping your dying grandpa? Why wouldn't you want to help him?
It can be difficult to help family members.
You know that one day you will be older too, right? You should want to take care of your older and dying family members, because at some point you will need that same kindness done for you. It's wrong to leave family behind just because it feels inconvenient to you.
I just want to party and go to clubs.
It is wrong to abandon people in need to go party. It would be so hurtful if something happened and you weren't there to help like if he fell but you were out getting drunk.
