A、Because he went to Lake Placid two hundred miles away. B、Because he discussed philosophy with his friends in a coffee house. C

M: I’m sorry. I didn’t plan on being this late.
W: Where did you go?
M: North.
W: We’d like a little more to go on, Mike.
M: Ok, I went to Lake Placid (22) .
W: Lake Placid is over two hundred miles away (22) .
M: Which is the reason why I’m so late. Look, I was at college, and me and a couple of the other guys were hanging out at a coffee house discussing philosophy and junk like that (23) when somebody mentioned that they got the first seasons snow on Lake Placid. So since I didn’t have an afternoon class, we decided to…
W: You have sociology on Wednesdays.
M: No. I dropped that class weeks ago.
W: You dropped sociology? Do you think that now you’re in college, you can do whatever you like, come and go whenever you like, no questions asked?
M: Pretty much, yeah.
W: How do you expect to be awake for economics in 5 hours?
M: Mum, I’m not nearly as irresponsible as you think. It just so happens that I dropped that class two weeks ago too (24) . So, anyway…
W: So you dropped two classes, without even telling me?
M: It’s not like I’m keeping it from you. I mean hey, college doesn’t mind if I drop a class here or there. My writing professor even told me if I didn’t care about his class, don’t come.
W: That’s it. You’re grounded.
M: I’m what?
W: Grounded. Remember, grounded? No dates, no parties, no life (25) .
