I too have some bittersweet.
Joined up the work volleyball team. It's been a loooong time since I last played volleyball, but managed to pick it up again pretty quickly. 2 hours of solid training and out-of-shape me is feeling it already. Feet are so and muscles too, but it was good bonding with the work buddies. Later we went out for okonomiyaki!
(the bittersweet bit is that I'm in a bit of pain)
Oh it was also very humid. Very, very humid and hot.
