I agree with this completely!!!

it's not just about grandma. Dad is having a hard time also, and would feel better about you going.

Also - there may come a time in your life when you will regret not going.

No one has any right to judge you for your decision. But I would advise you to go before it's too late and you regret it. Take all the good memories you have, and tuck them away. Don't let grandma now rob you of the grandma you used to have.

And be friendly with dad. He is having a hard time too. As dificult as this is for you to go through, think about how hard this is for him.
