My mother was a well-deserved donor of our country. Her blood was quite rare - 4 groups. Once, I remember, she was even sent by helicopter at night to some small town to rescue a child.

Parents always joked about the topic that my mom has the fourth blood group, and my dad has the first.

So here.

At a biology class at 7 a biologist offered to donate a drop of blood in order to determine the group. I was not scared, and it turned out that I had 4 groups, like my mom. It was also revealed (from the table) that parents with 1 and 4 blood groups cannot have a child with 4 blood groups.

I went home and began to torture my parents about who my real dad and mom are.

The parents were in shock, there was a small scandal. DNA testing was not as available then as it is now.

My father was sent to donate blood.

He has two blood types.

Everyone breathed out with relief.
