Stupid mistakes I have made while in the country:
1. Left apartment room with keys inside. Draught closed the door, which then locked automatically. Every room locks automatically in the apartment.
2. Went out for sightseeing on Pentecost, a public holiday in Finland. Finns are serious about holidays.
3. Boarded bus 280e thinking it would lead to Espoo central, but ended up in the countryside in Kirkkonummi. Return trip cost €7.20. I was lucky to have a return trip at all.
4. Tried drawing money from debit card when I had disabled drawing money overseas.
5. Walked into Greenbike with not enough cash.
6. Bought skimmed milk, taking it to be normal milk.
7. Poured 3-month overdue milk into coffee.
8. Put four electrons into the same quantum state.
9. Sat next to American tourists on bus.
