Once I went out for a ride, chugged around for about 3 hours, got back to my village and remembered I wanted to get some bread before coming back to my apartment.
Went to shop, lock out, hand in pocket for key.
No key. Pocket zippier was open.
Either I'd left the key at the apartment, in which case the door was unlocked, or the key was somewhere on the ground in the 20 odd kilometre route. The second of these was the more worrying.
Back on bike, race across village, through gate around to apartment door.
Door wide open, key in lock.
Inside, computer on table, work smart phone on charger.
