Just because you've been close to someone for years doesn't mean you know them inside and out. These still waters run deep, and there are new depths you'll catch a glimpse of today. They'll impress you and serve as an inspiration with an unexpected act. You might never fully understand who they are: but instead of being sad, this realization is somewhat exciting. Why not cultivate your own skills in a new endeavor? It's the perfect day to pick up a new hobby that will surprise people.
