Can I be yang today?

My first thought upon waking this morning was of my son. He was the last thought before I went to sleep last night, and I dreamt of him in the night, so it was only fitting that I woke up with his name on my lips. I lay in my bed for twenty minutes, my alarm blaring, and didn’t budge. Finally, I decided that calling my job with “I’m sorry, I can’t come in today, this is my sons birthday.” wasn’t going to work.
