The story I imagined while drawing this was as follows:

These people didn't yet know each other four days ago, but now they're like they'd been friends always. They were travelling on a ferry, sailing from Athens to Tel Aviv, but the ferry broke down and they had to come to shore unexpectedly in Port Said, Egypt. They're killing time in a hostel, waiting for the next ferry that's due tomorrow. They're strangers united by a chance, but they all share the passion for seeing as much of the world as possible while they can.

This exact incident hasn't happened to me, but it's nevertheless one of the sorts of things that happen on regular basis while travelling, which just makes it all the more interesting.
