I think there is a good chance that she is lying...however, I also think you should keep it to yourself. It might be annoying and pathetic and, unless you actually did lose a family member in the attack, to where her saying stuff like this would directly offend you, it's better to say nothing. I mean, if she's just saying it for attention, then she's probably got pretty deep rooted issues for making something like this up...feel bad for her, but don't say something and create unnecessary drama.
No, there were no survivors. If you're on a plane that hits a building at 500 mph, there is no way you're going to survive...but I think you should just ignore that girl, and not actually tell her she's lying. She could be lying for attention, or she could be confused and for some reason think her grandma was on a plane, but perhaps she was in a building instead. Or, if the grandma has alzeimer's, she might say stuff that isn't true that she thinks is true in her mind.
Nope, not one person did. You could call her out on it, but she may actually believe this. Or it could be for attention.
If she was told this by her family, stay quiet.
If you think its just for attention tell her that no one survived the plane crashes.
I don't think anyone survived on any of the planes
She's just some girl on Facebook. It isn't your place to point it out. You don't know who made up the lie, so let it lie.(no pun intended)
some girl on facebook is saying that her grandma was on that plane but is still alive and suffers from alzeihmers did anybody even surivee or is she just wanting to get the attention ?
