Dear Big Mac,
People like you should come with a warning label.
It would read:
Warning!
This individual is brilliant, hilarious, warm, loving, and gives the best damn hugs in the world, BUT he will break your heart. He will make you love him, but he does not love himself. He decided years ago that he would die young, and he is going to make sure his own prediction comes true. He will ignore his medications, his diabetes, his weight, his heart, his gout, his blood pressure, and when you try to talk to him about it all he will ignore you, too.
When you hear he's had a heart attack, you will curse and want to shake him, and then you will want to cry, because despite it all.. you are glad you love him. You just wish he loved himself, too.
