Question 2:

my second question is... If you went back in time and (OH) killed your grandma, would you be alive or not? because if u do kill her, then u would not be alive to kill her in the first place, so u wouldn't have, so u would still be alive to kill her, so u wouldn't be alive to kill her, so u would still be alive... so that's my second Q. good luck (u will need it!!!).
