<human>: Condense the text into a few key points

When I was in second grade, my class and I went on a field trip to the Liberty Science Center in Jersey City, NJ. Our school was about an hour away from the museum. On the bus ride there, I had told one of the chaperones that I felt sick and needed to go home. I was nauseous and wanted to see the nurse. The principal of the school drove 45 minutes from the school to come and pick me up, and I delayed the entire class trip; about 600 students were waiting on me to be picked up because all of the buses had to stop and wait for me. I felt terrible, all of my classmates were so excited to go. Some guilt was instilled on me that day, and now, almost 15 years later, that same guilt still lives with me.

I believe because of this trip, I have made a specific point in my existence to never be late for any of my meetings or appointments because of the fear that I may be keeping someone waiting. It pains me to think that someone could be upset that I didn't show up exactly when I promised to arrive.
