My brother is significantly quieter than I am, so you wouldn’t necessarily know how protective he is.
But at my wedding, he came up to me and my new husband and joked around about that scene in the first season of "Breaking Bad"when the characters use the wrong type of tub when trying to get rid of a body and the acid sips through the entire house. He laughed then looked my husband in the eyes and said, “I’ll use the right tub,” then walked away.
He was, of course, joking around. But he in his own dark sense of humor way, he wanted to get across the point that he will always have my back.
Brothers are awesome like that.
