I know I'm with the right person when I can be completely myself without worrying what my partner thinks. In other words, I can randomly quote lines from movies and/or songs, knowing full well that she won't run away (too far)
Some other hobbies I enjoy are taking foreign languages (have been taking one for the past couple of years) along with calligraphy. I find it to be extremely beautiful. It's truly an art form. I get the "artsy" gene from my dad's side of the family. Many are either painters, photographers, etc.
