Great, everyone thinks I'm crazy

[A co-worker and I had camped out in my boss' office for some group testing. He stepped out of the office for a minute, and my boss came back in.]
Me, after boss walks into his office: We can leave.
Boss: No, it's okay. (pause) You're the only one in here.
Boss' boss: Maybe it's time to start thinking about vacation.

[My boss left, my co-worker and I had done some testing, and then he left to get his laptop fixed. My boss came back later.]
Boss: Are your friends still here?
