Although a skillful flatterer is a most delightful companion if you have him all to yourself, his taste becomes very doubtful when he takes to complimenting other people.
Most important, though, I had to wait until I found the perfect traveling/eating/drinking/napping companion. And I did finally find him, two years ago - my Brazilian-born, French-speaking, wine-worshipping, tripe-consuming, uncomplaining traveler of a sweetheart.
I'm constantly on the hunt for insights about happiness or ideas about how to be happier - which probably makes me a somewhat tiresome companion at times.
