I feel like I should lock my grandfather's wife out of the hospital room and then refuse to allow her to attend the funeral.
What makes you want to lock out your grandfather's wife like that?
She creates massive drama all the time and she doesn't know how to respect the close ones.
You shouldn't disrespect your grandparents like that. Don't lock them out of a room. It's wrong, even if they do cause drama.
That's bullshit. I don't care what you think.
It seems like you're the one causing drama here, does it not? Your grandfather would want someone he loved enough to date until the end at his funeral, and it is very wrong to disrespect her by not only locking her out of his room but keeping her from his funeral.
