If it was my last day on earth before it ends, i would stop being shy and say goodbye to my family, and no matter where we go, i want to forever be with them. Especially my cats. They are so nice to me, i would make sure everyone has the best day of their lives
I would also probably shed tears and do whatever my brother wanted instead of what i want, because i always force him to do what i want instead of what he wants. I never know what i have until it is almost gone. (or in this case, until i think about all life on earth ending.) I would also post a goodbye video on all the websites i love. And tell them i love them and hope to see them in heaven.
