Tandinmother

Here is a journal entry from one of my students, a boy:

"I have problem of my mother and father. Once there was woman called Tandinmother. One night my father went to shop and buy many things. When he came back my father saw nice girl called Tandin mother. Then they are loveing together. I asked what happened to you? You are too late. Then my father said I saw one nice girl. Her name is Tandinmother."
