I was sitting in a café in the Montmartre neighborhood of Paris when I met Olivier. He was a few tables away from me and my friend, and had been laughing at my friend's attempt to pick up the waiter with her broken French. I had been doing my best to translate between the two and convey their mutual interest, but I was failing miserably. Olivier's laughter made me realize he understood both French and English, so I suggested he come to our end of the café and take over playing matchmaker. So he did.
