In a relationship when things are really great you don't need to say anything and just enjoy the other person. Sometimes with a couple, it gets dark and you don't know what to say and that silence can last all day. Other times you don't want to stop talking because you don't want to lose one another.
My playing music is strictly for fun. When I was in a band, I was really excited to talk about it since I had never really played music to that extent. It was never meant as something I would consider as anything more than having fun with my friends. But I think I would enjoy writing music for the movies that I'm working on.
