It's time for a Chinese test again

A foreigner studied Chinese for 10 years and came to China to take a Chinese proficiency test. One of the questions: Please explain the meaning of each '意思' (yìsi - meaning/intention/fun) in the following dialogue: Leader: "What do you mean by this?" Adai: "It doesn't mean much, just a small token of appreciation." Leader: "This isn't enough." Adai: "It's just a small gesture." Leader: "You're a really interesting person." Adai: "Actually, there's no other intention." Leader: "Then I'll feel a bit embarrassed." Adai: "I'm the one who should be embarrassed." The foreigner was completely confused after hearing this. He found it too profound, so he submitted a blank paper and returned home.
