Mother-in-law is not a classic of mother. Tell me about it.

It is the same reason that a mother-in-law is not a mother. Mother-in-law can never be her own mother, because fat mother-in-law and daughter-in-law are not related by blood, and even the best relationship between mother-in-law and daughter-in-law is only polite, not as affectionate as mother and daughter. Therefore, a daughter-in-law should not ask her mother-in-law to treat herself like a mother, nor should I ask her daughter-in-law to treat her mother-in-law like her own.
