Is this supposed to make me laugh?

Hettie asked me, "Mommy are you afraid" and I said "No, because I know you will be just fine". Then they asked her if she would like to have Laughing Gas. She said, "Is it funny?" They gave her the nose piece and had her start to breathe. After a small time had passed, she asked me with a concerned look on her face; "Is this supposed to make me laugh because it's kind of just making me feel sleepy?" :)
