W: Hey, Geff. Have you been to the new library yet?
M: Oh, hi, Jen. Yes, I went last week to check it out. I really like it.
W: Yes, I like it too. I like the study areas. There seems to be a lot of room to just spread out and focus on the books. It’s much better than the old library where it seemed like we were all jammed into one area. Sometimes it was even hard to find a spot to study because it was so crowded, especially during exams.[13]I even like the chairs at the new place. They’re super comfy.
M: You’re right. The only bad thing about it is that it’s pretty far away. It takes me about twenty minutes to get there by bus. So, I can see myself not going all the way downtown if I’m in a pinch for time. I’d probably just stay in residence and study there.
W: I was thinking that too. It’s too bad it takes so long to get there. I don’t like being dependent on the buses. Have you tried riding your bike there? It might take a little longer but at least you’re getting a bit of exercise.
M: That’s a good idea, Jen. Maybe I’ll try riding this week. I just have to make sure I’m good and rested. Sometimes, when I’m overtired I’m not too coordinated. Knowing me, I’d have a load of books in my backpack and get distracted by something and crash my bike.
W: Hmm. Well, you’ve just got to keep an eye out for those potholes. Oh, wow. [15]Look at the time! I’ve got to get to my next class. I’ll see you around, Geff.
M: Good talking to you, Jen. I’ll be seeing you.
