My husband and I are both the oldest siblings in our families. My husband definitely acts like the description, while I am far more like the youngest sibling (though I have learned to take responsibility and be in balance instead of at extremes). My H is the one who walked away, something that shocked me to the core. I'd thought of it, but he was the one who did it. That 180 of his saved our M.
