Can you be more stupid?

Here I am, finally sitting in my room. Everything is unpacked and cosy. However, this was not the case yesterday when I arrived from Sweden. On the train back to The Hague, I realised that I'd forgotten my keys in Sweden. "Oh fucking shit, shit. shit. shit. Fuck." was what was going through my head at that moment. How could I be so stupid that I put out the keys from my purse? Anyway, I slept at a friend's place and this morning I went on a hunt for spare keys. Duwo had spare keys, but had given them to some company that were going to fix something in the apartment. So I had to go back to the apartment and wait for the company there. Safe to say I'm never ever going to make that mistake again! Now when I'm all settled and home again, I'm gonna start studying for the exams next week!
