Yesterday, I overheard the conversation between my friends Jim and Rose:
Jim: I know lots of games.
Rose: Wow, let's play some.
Jim: If Jack too was here, it would have been great fun.
Rose: Oh, I miss Jack a lot.
Jim: He came last week for the exams.
Rose: Ha! Really? He didn't tell me.
Jim: He asked for a tea party.
Rose: Yes, it should be arranged.
Jim: Let's go at 4:00pm. He must be at home at that time.
Rose: He has nailed the exams and so he should be hosting the party, right?
Jim: Yup, and I bought a pen for him to appreciate his success in the exams.
Rose: Oh, great. Let me see it.
Jim: Aha, you lost. I am the winner.
What game they were playing? How did Rose lose and Jim win? And how does this conversation make sense?
