I'm a full time student, so I have a pretty busy schedule. I enjoy physical activities, so going to the park and playing catch or something more rigorious to have fun and keep in shape is something i live by. I go out and have fun when I can, though I'm trying to focus more on school now, to get my degree, then off to grad school.
If school isn't a factor, I enjoy going out constantly, I hate the feeling of being confined in the house -all- day. Doesn't mean I don't enjoy staying in and watchin a movie or playin a few games, but if someone decides to stay indoors on a great sunny day...it's just a horrible waste in my eyes.
Well, by the time I'd ask out said girl, I'd get a feeling of what kind of activities she likes, and maybe focus around that. In general, I would say that if it's a nice day outside, maybe a walk through the park, picnic, and something else. At night, maybe a stroll through downtown and grab a bite to eat. Simple, comfortable, maybe a little romantic. The point is to get to know each other, right?
