I was 12. My mother sent me to the store. Among the purchases, two-thirds of the "doctoral" stick was heard.

Arriving at the sausage department, I expressed my desire to buy two-thirds of the "doctoral" stick.

The seller stumbled for a few seconds and asked: half or a little less?

No, not two thirds.

The seller looked at the sausage and the knife. I put the knife on a quarter of the stick.

The Seller: So much?

I have already fallen into a stupor. Either they mock me, or she doesn’t really know how much “two-thirds” is.

I became a little uncomfortable. Looking to the side, I saw her partner who was looking at her colleague with a confused smile.

I: If I divide the rod into three parts, I have two parts of these three.

The seller thought about it, then made a hint on a third of the stick and was going to make another one in the middle of the remaining part, as she was quickly caught by her partner.

The partner: Stand up! Cut where you made the mark!

It cut off.

The girlfriend floated in a smile.

Partner: Now give him most of it, and put the rest on the window.

The seller gave me a sausage. But it was seen by her that the connection between 2/3 and the manipulations made was not finally reached to her.
