Team sports aren't my thing. I find it easier to pick something up if I can do it at my own speed. And you don't need a partner to go running you don't need a particular place like in tennis just a pair of trainers.
I'm not at the point where I'd feel safe in a house alone. I would be really scared. I'm the kind of person that when I get up to go use the bathroom I have this big long hallway and I just know someone's going to jump out and get me.
