When this man is conflicted, he asks Reddit:
So to start let me preface this by saying that my sister has been married to Hank for over 6 years. They have 2 kids and one on the way.
I visit her almost daily and I noticed that my BIL does little to nothing around the house or even child care. To give some examples...one time my nephew fell off the stairs and didn't need a hospital but needed immediate care from one of the parents.
My sister was literally stuck helping my niece out of the barn and BIL just sat infront of the tv shrugging it off. I was stunned that I had to go help my nephew out. Not just that but even now that my sister is 7 months pregnant. He keeps making her lift heavy things, run after the kids, bath them and cook for them.
