I was asked one thing from my daughter.
She met some girls when she played with her daughter near the house.
They are in elementary school girls.
They speaking very bad language to her and a daughter.
So she scolded them by same kind of language.
Then she thought what should I done at that situation.
And asked it to me.
I answerd....
Their paarents allow them to use that language.
You shouldn't have anthing to do with their parents.
If you speak same language with them, people will think you are the same type.
You should speak politely and like a teacher would speak to a child.
I bet that's a best answer to her.
