Wild swimming is gorgeous and quite warm right now.
Mine is afternoon tea. It looks lovely but I hate sandwiches and feel sick if I eat more than a small amount of cake.
Also hot chocolate in a cafe. I visualise leisurely sipping it, but it's never hot enough to do that and most cafes are full of other people being annoying by talking loudly and dithering in the queue.
I have to remind myself that both are disappointing experiences.
