Full of regret
It can be the most annoying and frustrating thing in the world to start a job enthusiastically and then get to a point where you can go no further. This tenant asked her landlord to fix her doorbell, which would seem like a pretty simple request. It’s always helpful to be able to hear visitors when they come to the door.
The landlord started enthusiastically but was not able to fix the problem. This is fair enough, not everyone is a natural electrician. However, instead of admitting defeat and calling in the professionals, he wrote a little note to visitors so that they could connect the circuit themselves. It might be just me, but this doesn’t feel safe.
