Niece's pictures, and her "puppo" literally release oxytocin in me. This is purely biological love. I am sure being a parent means having your heart explode with love. 

My schedule has made it impossible for me to hear niece's voice over the phone. By the time I am done, she is already in bed. And I have already started thinking of finding ways around it. I rarely talk to my own siblings as much as I want to talk to this one. Have never known love like this.
