Okay, so I'm writing this quite quickly, so I apologize beforehand if you spot some grammatic fails

Alright, quick intro. So, basically my grandmother (who is actually quite old, 86 years old, but super sporty and hyper) was admitted to hospital earlier today duo to a heart attack. Just last week, she was admitted to the hospital for a pneumonia, and we found out that her blood pressure was quite high (higher than normal). She's quite sporty for her age, she would walk around quite fastly, taking care of my sick grandfather and also do some morning stretches and make food (like 5 times a day). Now that she's in hospital for the second time in two weeks, we're all waiting for the worst. It's quite a shock actually.

Okay, but to the real point. So, my father and some of his siblings are not exactly on the talking terms. They haven't been for 5 years. And uncle of mine (their brother) has already passed away last November, and then my grandmother's sister and brother. But this is their mother. They're still not in talking terms, but this may be one of their mother's last days, and the least I want is to see her worry about her children that can't get along. So... I guess, I was thinking about bringing my father and his siblings back together, at least try, just this one time. Just for my grandmother. She's loves her children like no other, she cried every time my dad and his siblings would fight, and think about how much she's hurting now, knowing that she's about to go and yet her children aren't getting slong.

She's so sweet towards everyone, especially her grandchildren, and I can't let her pass with a heavy heart. So... Back to my plan... Should I do it? I mean, I know I shouldn't interfer with the "adult's fight" but... It's my grandmother. 

What do you think I should do?
