Uncontrollable Phenomenon

After a long day at work and arriving home past Justin's bed time, I notice an interesting phenomenon. The moment I laid my eyes on him, a smile appears on my face for which I have no control over. I was clearly smiling because my eyes are looking down my cheeks but my brain cannot comprehend why.

A smile from the heart.

A phenomenon that is new. 

I can get used to this.

~Good night, my little man. See you tomorrow.
