Habits can be healthy, harmful, and even strange or ridiculous. It is the latter that we will talk about.
The thing is that careless manners and thoughtless actions can tell more about a person than he is trying to hide, for example, about his level of intelligence.
You can know all the noble manners by heart, bow when you meet and cough into a napkin, but taking a shower once can ruin the whole impression.
A strange combination that, in principle, cannot have anything in common.
However, the habit of leaving a dirty bathtub or shower stall after yourself speaks of worse qualities.
Firstly, the habit of leaving hair in the bathroom after washing indicates low intelligence.
Secondly, puddles left on the floor from wet feet indicate that the person is not worried about someone slipping on the wet floor.
Both of these habits indicate that the person has a complete lack of empathy and does not care about the consequences of his actions.
All together this is already a sign of low intelligence and laziness.
But these habits should not be confused with forgetfulness and lack of time.
Only if the situation repeats itself day after day can one draw such unpleasant conclusions.
