To be authentic, remember this

Who all said that authenticity requires seriousness in speech?

No way!

People tell you that in order to connect with people, you need to be authentic.

Well, they also need to tell you that in order to be authentic with them, you need to bring out the fun side of you.

Bring out the one-liner, fun side of you, time and again, and people will remember you because you were a human, a real intellingence, not an artificial intelligence.
