I hate people eating my food. I feel sick after they eat it and I won’t touch it again, even if I only take one bite.

It is normal to feel disgusted by others picking their noses. Except for a small number of sloppy people who do not pay attention to personal hygiene, they will be disgusted.

But... this toothpaste is a bit serious. It seems that your mysophobia is really serious.

I admit that I have mysophobia and I have to take more than two baths every day. Also once a day in winter.

But I am not exaggerating like you,

But this is also a good habit to isolate infectious diseases.

Just toothpaste is not necessary, although you said this habit is very helpless.

But this kind of behavior hurts parents after all.

You also know that there is nothing wrong with them, so why don’t you work hard to get better?

Actually, the other things you mentioned, like not giving others your own food, like not eating what others have eaten, are the same for me.

These are normal.

Only the one squeezing out toothpaste, tsk tsk, really needs to change.

If you really can't change it, then have a good talk with your parents.

Just say that this has become a habit for you, and pay attention to your tone to be calm and helpless.

Don’t be assertive, it will of course lead to quarrels.

Finally, let me tell you a joke in this regard:

The mother fly and her son were having a meal, and the little fly said to his mother with a sad face: "Mom, why do we have to eat feces every meal? ?"

Mother Fly was furious: "Don't say such disgusting things while eating!"

You know- - Ahem, this joke seems a bit disgusting. Hope you like it.
