The mystery of the unlocked door

One door lock suddenly cannot lock, the locksmith is on the way, but I am left wondering what on earth has happened.

It worked fine this morning, and this afternoon, the key looks undamaged, but the lock reacts as if the key had broken and half was inside the lock keeping it from locking. Weird.

I’m going to be looking the locksmith over the shoulder to see what on earth can have happened.

Thank heavens backpackers are resourceful people who take such things in their stride.

I wonder why things like this only happen when we are fully booked.
