<human>: Can you provide a brief rundown of the text in within 3 sentences?

**Context** : took a bus from Stuttgart airport to my German hometown, stopped in another town to take a connecting bus.

Coming back from my holiday, I decided to take a bus from the airport. My suitcase was really heavy, thank God the driver was here to help all travelers put their luggage in the baggage hold after such a long flight.

Here comes the fuck up. The bus made a stop in a connecting town (Karlsruhe), where I would take another one in order to make it to my hometown. The bus driver opened the baggage hold and took a smoke break. So I had to take my luggage by myself. There was another black suitcase above mine, I took it and put it on the sidewalk so I could reach mine.

And the bus left. I only realized my fuck-up when my other bus arrived, as the driver asked if the black suitcase belonged to someone from his vehicle. Every traveler claimed it wasn't his, then someone said "It was already here when we arrived, someone must have forgotten it from the previous bus."

***Oh shit***. It was the one I forgot to put back in the hold after I took mine. The unlucky traveler had a further destination, of course he didn't exit the bus and see his luggage being taken out by mistake.
Even worse, this person was traveling to Frankfurt Airport (as my stop was the last before the terminus). 
*If you're reading this, sorry for making you panic and likely miss your flight.
