I'm 27, single, with a rich social life. Obsessed with my projects. Hide it from just about everyone. I've tried to show friends my projects, but most seem unimpressed or disapproving of the childish hobby, so I stopped doing that. And to clarify the ridiculous discrepancy here, I have friends who own a room full of transformers, make papercraft, knit, collect anime girl figurines, play with nerf guns, and other strange hobbies. Yet mine is mostly considered child's play and is met with bored or disapproving looks :/ I think it's 50/50 that I'll stay in the hobby more than a few more years. I'm pretty ADD with hobbies. But more likely, I'll probably enter a second dark ages, then come back to it again :D Even though I won't give up the hobby because of what people think, I still weigh the costs and benefits of publicly sharing it. I don't mind keeping it private.
