The harm to your niece
I have nieces. She's a seven-year-old girl in love, modest, kind, lovely, polite. She was brought up in such a way that she doesn't pay attention to material things, she doesn't really care about the latest technologies such as tablets or "aj fon", she just needs a simple button phone from which she can call her mother or grandmother.
Recently she told me that she doesn't have any friends, just because she is a little taller and doesn't have a cool phone.
I'm so sorry to hear that she's sitting with a friend on the bench who doesn't like her and she's sad.
Where is this world going, that even small children, the kids we love, look at other people from a material point of view. It's so sad...
