Person2:Oh , hey , no kidding ! I haven't seen you since orientation three months ago ! So how've you been ? Settling into college life OK ?
Person1: Yeah , I think so ! I pledged Phi Iota Alpha , so I'm living at the frat house now .
Person2:Oh , so you're a frat boy now , huh ?
Person1: Yeah , yeah , I know , it's totally cliche , but really , I think it's been a good decision . I've got a lot of support and good suggestions from the guys . What about you ? What have you been up to ?
Person2:Not much . I'm still living at home and commuting to school . I ended up dropping that metalworking class I was so excited about . It just wasn't as interesting as I'd hoped . The guidance counselor suggested that I focus on my prerequisite courses so that I can make sure the credits count .
Person1: That sounds smart ... but kind of boring .
Person2:Yeah , it is , a little bit . I joined the Great Outdoors Club , though , which has been a lot of fun . We've gone on two camping trips already , and I've made some good friends .
Person1: That's cool . Hey , so have you decided on your major yet ?
Person2:Definitely pre-med . What about you ?
Person1: I still have no clue ... but we don't have to declare a major till our sophomore year , so I've got time ! Oops , I'm late for class . Gotta run !
Person2:OK , take care ! Hey , nice running into you !
Person1: Yeah , you too !
