He doesn t flush the toilet all the time, what should I do?

Make a more cartoon brand. Write: Rush! Rush! Rush! Come on!! Thank you!

Then hang it on the wall that he can see when he excretes. Guaranteed results. It doesn't hurt the peace.

You don't say anything, in front of him, without any expression, you wash it away. Silently express your displeasure. Once or twice, he will be embarrassed and will come to his senses. When he said, "I'll come, I'll rush." , achieved the goal without hurting the peace.

You can tell him, and if you get rid of this bad problem, it will be a good habit for him. He should be able to understand you!

Take a step back and open the sky, be generous enough to tolerate the world, and use your own practical actions to influence others!

It's not your family???

It's not your family who has to tell him that it won't hurt him, but he'll feel embarrassed.

I don't think you should close the door and don't ask about the world, no matter how you say it, it's also a roommate Occasionally joking, naturally there are some things to talk about, and if you say what you want to say in a joke, I don't think he will care about anything. But he will know in his heart.

You don't rush either, and let him taste the embarrassing scene.
