Guys I know this may seem random but no matter how much you hate a sibling or parent enjoy your time and good moments with them while you can because that moment could be their last and everything you did together would have been for nothing, so for both your's and that family member's sake enjoy them while you can and always say I love you because if you don't, and they die, you won't get another chance to...ever again.....
And when they die it hurts so much...
I know because I'm speaking from experience.......
