A couple years ago, I was on a tour of the National Weather Service office in St Louis. My dad and I were talking to one of the meteorologists about my possible career paths and requirements for a while (half hour or so). It was probably about 85 degrees with sun on us the whole time.
Finally, the tour started. We went inside the building with a group of about 30 people while another meteorologist handled the tour. He was just talking, I was in the middle of the crowd. I suddenly started to feel mentally strange though, like I was about to tear out of my skin and go insane. I kept looking up at the guy and was like "WHEN WILL THE DOLT STOP TALKING?!" in my mind, when normally I can sit listening for hours.
I started to move through people to the back of the small room. I kept looking at everyone with some sort of hateful passion wishing they would just get away from me. I started to feel kind of dizzy. I turned to my mom and said under my breath, "I need to get out of here now."
Normally, I'd never voice my opinions if I hate something in public, and she was somewhat alarmed and replied with, "What? Why?"
"I just need to go, right now."
She started to lead me out the door. Right outside the first doorway, but before I left the building, I passed out and smashed my face into a window. Everybody in the whole building saw me. When I woke up, my mom was going crazy, my dad was in my face, and there were two teenage girls and the meteorologist guy right behind him. I was taken outside cause my parents thought I would get sick, but I didn't.
They contemplated taking me to the emergency room, but I said no. We went back inside where I was sat down in somebody's desk (probably the secretary's). I had a cup of water with a mountain of ice in it and I watched two more tours go past. Eventually I decided to get up and went through with the next group that came through.
I think I was asked about 500 times, "Are you ok?" for the next couple days. I conclude that I probably had really bad heat exhaustion because I had nothing to drink that entire day.
