No Intention

I called Andrew. I could hear pleasure in his voice when I announced who I was.  

"First of all, I want to tell you how much I enjoyed our lunch last week. I'm nearly obsessed with it, cannot let it go. Second, before I go any further, I want to make sure you know I had no intention of having lunch with anyone that day and that our meeting was not for the purpose of gathering another lunch story for my book. That isn't the way it works. Every encounter is random."

"I understand," he said. 

"I don't want you ever to think I used you. Plain and simple, I was moved to ask you to join me." 

What do you think moved me to ask Andrew, a perfect stranger, to join me for lunch?
