You're my brother or sister, I'm a couple of years older than you. I'm not hostile to you, I'm used to being present, and to the fact that my dad is married to your mom. I treat you neutrally, as you treat me, so I treat you. I smoke sometimes and keep it a secret from my father. I can help you with anything if you need it and I share the household chores. I really like the fact that we are a family, and I have nothing to complain about. Maybe you can get to know me better.
