1. Cooking dinner and seeing someone else enjoying it.
2. Longterm 3BTers may remember the transports of delight I experienced in Africa when a male vervet monkey stalked past me with his bright blue balls on display. Imagine, then, my jaw hitting the floor as in the course of the BBC's wonderful and highly educational The Life of Mammals, David Attenborough narrated very delicately footage of right whales mating. Twelve feet long and highly mobile, apparently.
3. My laptop now has a reliable source of internet that really belongs to us.
