Tim: Hey, how do you and your friends get along?
Mary: Well, it's easy, you have to spend a substantial amount of time with them like going to the movies together, shopping or maybe just chatting on the phone.
Tim: Oh, I see, anything else?
Mary: Hmm, it's just for the personal relationship, I guess basically, you just hang out with them and help them when they're in trouble, talk to them when they're in a bad mood. If it's for the romantic relationship that you have with a girl, then there're definitely a lot more things that you have to do.
Tim: Such as...?
Mary: Anything that you do to make her feel special!
2. Mary: Do you hope to have a perfect memory, Tim?
Tim: Yes, I do, my dear.
Mary: Why?
Tim: Why? Why not? You hope to have an imperfect memory, I mean?
Mary: Of course not, why would I want that?
Tim: That's right! So don't ask me silly questions like "Do you hope to have a perfect memory?"!
3. Mary: Tim, do you believe in alians?
Tim: You mean life out there in the outer space?
Mary: Yeah, don't you think that we are not alone in this universe and there're other life forms existing in some planets that are far away from us?
Tim: Well, that's very thought-provoking, but you make me feel creepy that some day I might get kidnapped by an UFO!
