TIFU I thought I was supposed to check out tomorrow, but it was actually today. I went out early for a hike, the hostel called the police thinking I had disappeared.

This is in a German national park. I've been staying at the hostel for a week-- no car. Because I had come back super late at night the previous day and left super early in the morning today, no-one working at the hostel had seen me since yesterday morning. When I got back today, they said "hey, why didn't you check out? we were worried, we thought you might have fallen while climbing, so we called the police. They were going to send a helicopter out for you." At first I thought it was totally crazy of them, but then realized that it was my check-out day and that I really was meant to leave with all my stuff in the morning, so of course they would freak out when they didn't see me.

TL;DR I thought I was supposed to check out the following day, the hostel was confused when they saw all my stuff in my bed, they called the police.
