"I don't know what love is, but..."

Riding the streetcar, occupying two facing seats across the aisle, is a developmentally disabled couple, probably in their mid-30s. 

He is engrossed in his XBox; she sings "Good times, good times", words without a tune.

Then she speaks to him, so loudly that the car easily hears: "I LOVE you, honey." He replies, not looking up, but equally audibly: "I love you too."

She speaks again, not addressing him, more softly, as if voicing a thought: "I don't know what love is, but..."

At the stop, he descends first, then extends his hand to help her navigate the steps.

I turn to the natty young businessman in the seat next to me and smile. "Yep!" he exclaims, as our eyes follow the couple, now walking hand in hand down the street.

Pondering love, indefinable, mysterious, yet deeply felt, each of us heads into our day. 

Happy Valentines' Day!
