<human>: Can you provide a brief overview of the text?

Excuse any grammar/spelling mistakes, but English is not my first language.

So last summer during exams I was running late in the morning and about to miss my train. So I had to run to arrive at the train station on time which is just about 500 metres away. To give you some additional information, It was end of June beginning of July which led me to show off what I have, especially wearing a shirt with a rather risky neckline (having quite an ample bosom). 

So I start rushing to the train. After about 300m I could already see that the train is already there and seemed to be about to leave. So I sped an and literally sprint the rest of the way. People I was passing pretty much stared at me, which I thought was due to my running. I could have gotten a little suspicious when I got to the train, apparently slowed down, and people continued doing that. I got in  snatched a seat and was heavily exhausted, but happy that I won't miss my exam. At this point there were some guys around pretty much still staring at me for some reason. A rather concerned looking lady on the seat opposite of mine, was shaking her head and pointing at me. At this point I looked down at me and realised that one of my boobs was just showing off on top of my shirt. And I'm not talking about a little bit, it was full on outside my shirt. It must have gone out during my run and I just did not realise up until now. So I covered it immediately, my face did turn red as fuck and I took my stuff and moved to a different carriage. Worst morning in my life!
<bot>: late for train, had to run, boob fell out of shirt and must have been swinging like a demolition ball right through the train station.
