I want to tell you I am a time traveler. I come from the year ad 2120.
That's interesting. I always wanted to meet a time traveler.
You should be happy that I am not a real time traveler.
Pretending to be a time traveler can be fun for a while, but the joke will get old if you persist with it for too long. It is good to know when to joke around and when to stop and be serious.
Haha, fine you caught me. It was just a joke. I'm actually an alien, who traveled here in a space ship.
Stop playing around. You need to be more honest with people and not think that they are all gullible.
