We had some practice in psychic.

I went to the female department. The teacher says:

Do you want me to tell you how old we are?

He calls a 15-year-old girl. The girl runs to us, slightly full, small in height, in the eyes a sea of naivety, a smile to the ears.

Q: This is our Olečka, she is an oligofren. Olive, how old are you?
