Activities with roommates....
Watching Sports!
Especially those played by younger siblings...
Rock wall climbing, basketball, and running are also activities that I enjoy.
Exploring the outdoors in the winter, slack-lining in the summer, and the occasional art project also keep me occupied.
The last and probably favorite hobby of mine is hosting meals. I love the experience of a group of people joining together to have good conversation over a warm home cooked meal.
