Bill and Steve are enjoying a beer and discussing the possibility of love. I thought I was in love three times, Bill says. Thought? Steve asks. What do you mean? Three years ago, I cared very deeply for a woman who wanted nothing to do with me, Bill says. Wasn't that love? Steve asks. No, that was obsession, Bill explains. Then two years ago, I cared very deeply for an attractive woman who didn't understand me. Wasn't that love? asks Steve. No, that was lust, Bill replies. And just last year, I met a woman while I was on a cruise. She was gorgeous, intelligent, a great conversationalist and had a super sense of humor. Everywhere I followed her on that ship, I would get a very strange sensation in the pit of my stomach. Well, wasn't that love, asks Steve. No. That was motion sickness! Bill replies.
