I don't know how he got this way

This kid was seriously the worst baby ever - he cried all the time and the highlight of my day was when someone came over and took him away from me for even five minutes. And I felt like a horrible person for hating this screaming bundle of "joy". 

This is what he said to me this morning:

"I always feel like my heart is a puzzle and everyone I love is a piece and you're the final piece that make the puzzle complete."
