There are ways to achieve the goal. I wonder if the landlord would like to try.

As long as you don't take a bath every day for 15 days, you will find that there is no need to take a bath at all.

Give it a try and give an evaluation after the exam, hehe.

Use shower gel for both baths, hehe. Once a day from now on.

In other words, you are not lazy. You take a bath every two days. You are diligent.
