A lack of composure is usually visible when someone begins their presentation and forgets what they planned to say, making it a very unprofessional and embarrassing moment.
Context: "I had to give a presentation at work that I really prepared for, but when I began it I forgot everything that I had planned on saying."
Hypothesis: I felt so confident when I began my presentation and couldn't remember anything that I had planned to say
