My parents are quite neutral when it comes to my hobbies: as long as I don't do anything illegal that's fine by them. They give me car rides to competitions and offer to pay the registration fee for me. They've also paid for my cubes etc. so I think they're happy that I finally found a hobby that I enjoy. However, I do have a story to tell.
So, a bit of background information: I've been cubing since I was 13, and I'm now 18 and living on my own. My parents are divorced and live in different cities. I lived with my mom who has a new boyfriend, let's call him B. B has some mental issues: he has narcissistic characteristics and he cannot stand if my mom pays more attention to me than to him, even just for ten minutes. If I'm meeting my mom or she gives me a ride somewhere, she always lies to B about where she is going and with whom. If she tells B she is meeting me, they'll have huge fight over why B cannot come with her. (Simply, because I want to spend time with my own mother, not with someone else.) He also wants to be the best in everything, in every way, and he wants to control their whole relationship. (Let's just say that it isn't a healthy relationship: they fight a lot and often it gets physical.) Also, he's one of the type of people that want to seem smart. (Emphasis on the word 'seem'. He doesn't actually try to improve his intellectual capacity for example by learning a new language or whatever. Instead he's trying to memorize the first 100 digits of pi or learns some interesting facts by heart, You know, he seems smart to others but actually he hasn't done anything but just memorized some facts.) B and I do not get along at all. I cannot stand the way he treats me and my mom, so I try to live like he does not exist.
Anyway, when I first solved the Rubik's cube when I was 13, I was ecstatic. I showed my mom the solved cube and said: "Look, I just solved the Rubik's cube". She didn't care that much about it, which made me a bit upset. However, I got hooked on cubing and in a few months I got faster and decided to buy a real speedcube. It was no secret in our household that I could solve a Rubik's cube in 30 seconds, which is rather impressive for non-cubers. So, no wonder I soon start to see our house filled with Rubik's cubes that are not mine--they're B's. B is learning how to solve the Rubik's cube.
I'm upset but still okay. It's fine. Anyone can learn to solve the Rubik's cube, and I cannot stop him doing that. Besides, speedcubing is still my hobby, and no one can take that away from me. However, B gets faster and soon he can solve the cube in just a few minutes, and eventually in under a minute. My mom is impressed. She's thrilled when B solves the cube. (Flashback to the time when I showed the solved cube to my mom and she couldn't care less... Ouch!) I feel attacked, defeated. I feel like there is nothing in this household that could only be mine, my personal space. My own dimension where I can be who I am, and not having to worry about B getting his hands on: when I got into physics and started reading "The Brief History of Time" and Feynman's lectures, a few months later B borrowed the exact same books from a local library. At some point I also wrote a diary where I could write what is going through in my mind and a few months later B is reading my personal diary.
And so, I quit cubing. It didn't feel like a hobby anymore. It felt like a competition for attention from my mom between me and B. And most importantly it didn't feel like my private space anymore.
Now that I'm living on my own I've gotten into cubing again. However, I've forgotten most of my algs for LL and my lookahead is terrible. My times are over 10 seconds worse that what they were two years ago when I stopped cubing. Still, I'm happy I got back. And as far as I know, B doesn't know there are these things called "speedcubing competitions" so there's still something in cubing that is only mine and not his.
