Unacceptable dozen of toilet paper

I am a relatively indifferent person and don't care too much about my daily image. Especially when I am in a neighborhood, I feel better. Things like shopping at the market with slippers and beach pants on weekends happen almost every week. But there is a behavior that I cannot do for the moment-buy a dozen of toilet paper to go home.

Why? I want to come and find out why. There is no problem when I buy a roll of toilet paper and put it in a plastic bag to pick it up. But I couldn't accept it because it was a big package in two rows. When I think that I carry these two lines of toilet paper with my hand or my arm's nest, and walk above the street with justice, I feel numb, and an unsigned heart comes to my heart, the hand that reaches the supermarket toilet paper shelf also naturally shrinks back. There should be little to do with this attribute of hygiene products. I don't feel embarrassed to help even mm buy tampon. How can I reject toilet paper thousands of miles away?

In short, it is a strange psychology. Maybe it comes from a forgotten childhood shadow? Or was it hurt by a dozen of toilet paper in a nightmare ?...... Another possibility is that I had obsessive-compulsive disorder like monk. He forced me to do something, and I forced myself not to do anything ...... Oh, my God!
