Enamored with the Andrew I met on the Train

I met Andrew about two weeks ago, on the train between Amsterdam and The Hague. We got engaged in a friendly conversation. He turned out to be from Australia, visiting the Netherlands and some other European destinations. We happen to - broadly - work in the same field; we immediately had some interesting views to exchange. He was interested in the book I was reading. We exchanged business cards. And then there was The Hague Central Station. The thought "invite hime for a drink" flashed through my head, but he had told me that he would leave the next day. So I thought that it would be best to wish him a safe jouney and let our paths part there.
WRONG! As much as my rational side is in denial (a stranger living on another continent on the other side of the globe?!), this desconocido touched something inside of me. Andrew is lingering on in my thoughts...
