Small problems become confident when neglect keeps proving nobody is coming.

A small problem left alone does not remain small. It expands into the space you have left it, precisely because nothing has pushed back, and by the time it is addressed it has established itself as a normal feature of the situation. This is true of leaks, of habits, and of how people treat you.

Ask what small thing you have tolerated so long that it has settled in. Push back once, clearly. Most of these test whether anyone is going to respond.
