This is random, but chance encounters with animals. There's a paddock abutting my backyard that rarely gets used, but sometimes there are a couple of horses that get turned out into it. I'm always excited to see them and would love to meet them if they come to the fence line!
Also, I don't do this often, but yesterday I took myself out for tea. There's a cute tea cottage not too far away that offers a four-course afternoon tea. First course is quiche with dressed greens, second is a scone with clotted cream and lemon curd, third is a variety of finger sandwiches, and fourth course is a variety of dessert bites. So I brought my kindle and drank an entire pot of tea over the course of the meal. It was a real indulgence and definitely made me happy to be alive ;)
