I was invited to give a workshop at LibertyJS in Philadelphia. This was a local event. The event gave me a free ticket, and I was not paid to speak. The event did not pay for my travel and accommodation. My employer did not pay my travel expenses, and I was a student when I spoke at the event. It took me 1 day to prepare for my 60 minutes speaking slot, and I had a mostly good time. I'm a human who has been speaking for 4 years.
