<human>: One day at recess, in first grade, my crush and her school yard entourage approached me. She told me to promise that I wouldn't laugh at what she was about to say, and I said of course I wouldn't. She then broke the news that she had liked me and thought I had a great sense of humor. I instantaneously unleashed my "sense of humor" on her and started hysterically laughing thinking that she would catch the drift that I was just laughing because she told me not to, and not because I found it funny. She broke out in tears. And it took her a few years to forgive me. Needless to say, that never worked out.

Could you distill the essence of the text into 1-3 sentences?
<bot>: I honestly thought I was funny enough to pull off laughing in my crush's face when she told me she liked me.
