I cried when I tried to get out of a conference talk and couldn't

I attended another conference this past week. It was very much the opposite of the conference I attended last month because it was much smaller, more focused, and was a basic science rather than clinically-focused conference. Despite having purposely submitted my poster abstract for this conference after the deadline to be considered for a short talk, my abstract was chosen. I cried when I got the email congratulating me on my interesting abstract. I cried when I tried to get out of the talk and couldn’t.
