moppy hair and freckles

in route to hoboken, standing on the path, I look down and see below me a short person about 22 years younger than me discussing submarines, bridges, and sunglasses with his father.

This person has a mop of curls covering his head, piercing blue eyes, and possibly freckles.

Dad: So the subway is like the bridge but underwater

little person: like a submarine?

Dad: exactly - it's like we're in a submarine

little person: oo that's weird

Dad: haha true it is kinda weird

other conversations ensued - as I eavesdropped.  

At one point, this wobbly, fairly new to walking, person's head grazed against my forearm and the softest hair i'd ever felt brushed against me.  4 year old product-less and innocent curly moppy hair.

At that moment, I wanted a little person of my own with soft hair to discuss submarines with...my eyes teared up, the subway stopped, and i hurried off to reach my other kid-free 20-somethings and forget about my random urge to procreate.   

i'm probably ovulating, hence the urge.
