Is this the female version of GYOW?

Don't write me off as a crazy hippie just yet! I'm a 39yo woman who owns a graphic/web design business with a good staff, so I have a lot of downtime. My sister has a wonderful 13yo who I adore and spend a lot of time with. Sister had an unexpected and complicated pregnancy, and our parents both passed away when we were teens, so they lived with me for the first 7ish years of her life, and they still have "their rooms" at my place. They live one block away.

I was briefly married, it ended very amicably. 13yo knows and loves him too. It's likely he will come back and settle down with me again, but his business took him all over the place and he felt weird being attached while being away for 6+ months at a time. I decided a long time ago that I didn't want kids, got myself fixed. I date occasionally (men & women), but it's never been a big thing for me. I love my life.

About two weeks ago, 13yo and I were sitting on the patio. She started asking questions about me, my life, etc. They ranged from "why don't you always shave your legs like mom does" and "why don't you have kids" and "when will you get married and have your own family?"

I gave her honest answers to each question that boiled down to: girl I just don't want to. That really surprised her, and she kept asking "But don't you have to?" and "But everyone else does." and "but don't other people make fun of you?"

Finally, I told her something like, "You don't always have to do what society tells you. Like yeah, you have to obey traffic laws, and don't go around being mean to people. But shaving? Nah. Getting married? Lot's of people don't! Having kids? You don't have to if you don't want to." I then spouted some hippie ass bullshit about "Your life belongs to you and you alone, don't ever let anyone pressure you to be someone you aren't. So if you WANT to shave your legs, don't let me change your mind. But know it's your choice."

She became very contemplative about things, asked some more questions, but eventually she told me about school crushes and shit.

I thought the conversation was totally fine until my sister came over and yelled at me for trying to turn her kid into some "hairy lesbian" who will never give her grandkids. I tried to explain that's not at all what I did but she completely blew up at me and told me they needed a break from me. They're usually over every few days or so, but it's been quiet. I'm very sad about it, but I honestly don't feel like I did anything wrong.

Did I, though?
