I don’t remember this story myself, since I was 3 or 4 years old then, so I recall my mother’s words.
One day my mother took me to a logopedist. The logopedist asks me:
How does the cow cry?
My mother says that’s how she formulated her question. Apparently, the word “mocking” would be a too clear hint. Therefore, in full accord with TZ, I replied:
Aaaah aaaah!
The logopedist, strangely enough, remained dissatisfied. I still do not understand why.
