When I was 12-13, I didn't like this either, but I stopped caring after a while. People would think I was older than I actually was, which I thought was pretty cool, so I just went with it. If you don't behave like a typical 12-13 year old, people won't think of you as one. Just don't consider...
You should get into the habit of using indentation so that your code is readable. I'm not sure about the specifics of Ruby, but I would do something like this:

lastnum = -1
My 6 year storebought is awesome. The pieces are crazy broken in, but the core became so springy that it started popping like crazy. I put the storebought cubies in my Type A core, and it's amazing. My main cube now.
2x2: 7.64, 6.18, 8.54, 6.97, 7.42 = 7.34
Comment: Not bad. I'm getting good at 2x2.
4x4: 2:20.34, 2:21.57, 2:29.13, 2:23.99, 2:26.00
Comment: I hate my 4x4 beyond words. Solving it frustrates me. Never lube Eastsheens; they will never be the same.
