Ten years ago tonight, it was storming. He arrived with a bouquet of lilies. We had met online, emailed, and spoken, and this was our first date. I suggested staying in instead of going out as planned; I could cook us dinner. The attraction was delightful; dinner was even eaten -- eventually. Christo and I became each other's "number one" for the next five years; then we were "exes with benefits"; now we are "friends for life."
When two people have business with each other, the connection is clear. The form, however, can, and often should, change. The majority of my best friends are my former partners and lovers. This surprises some people.
