The ever-expanding organ

I'm talking about the heart here, folks.

Isn't it just the most amazing thing?

There you are, completely in love with your partner. Your heart is full of him. Your life is complete.

Then, out of the blue, a kid happens. He pops out and as soon as your belly deflates and you see your little bundle of squealing joy you are completely smitten. Your heart, which you previously thought was full, suddenly expands and is full yet again. Amazing.

A few years pass, and another kid appears. You look at his little red squashed up face, tiny hands and feet and once again that heart of yours swells. You don't love your partner or other kids any less. There's suddenly just more love to go around. Perhaps you love your partner and kid even more with the appearance of this new face. Incredible!

And then the girl arrives. A squeaky little thing who grows into a squealing little toddler. And that heart of yours gets bigger again. How does it fit in your chest, it's so big?

And now, every time you see those three children play nicely together, watch the girl admire and copy her brothers, watch the boys laugh and co-operate, that little old heart expands again and again. Every time one of them says "I love you, Mama" it happens. Every spontaneous hug. Every proud moment.

It just amazes me so much, that ol' heart. Will it never stop expanding?
