Your family sounds exhausting -_-. Sounds like your sisters maybe shouldn't have had kids.
Both of my stepsisters are good parents (younger of the two had my niece at 17. She was basically a poster child of what teenage single mothers should be imo. Very proud of her) and their boyfriends are good guys (one is the father, one is not). My nephew unfortunately is a bit of a hellion and has a bunch of issues. Neither my brother or I ever want kids. He's bipolar and doesn't want to pass that on. I just don't like the idea of having kids.
I don't get why people shit on dyeing hair and equating it to anything other than "I want my hair to be this color instead."
Yeah my family is just weird. Glad to hear that yours is a bit different at least as far as your stepsisters are concerned :) ---
