A neighbour on my floor set his alarm clock and forgot all about it as he left to spend Christmas and New Year at home. Hence every morning if I step out into the corridors, I can hear this insistent alarm clock ringing. I didn't wander from door to door to listen carefully and confirm the exact apartment the alarm is coming from. There was no thought to summon the security guards to enter that apartment and deactivate the alarm clock.

Strange as it may seem, that alarm amuses me.
