What Are Mothers ?
Mother, the most common kind of mothers are the biological mothers. They give birth to their young and nurture them. Most biological mothers are kind, loving and caring. Even at their worst times, they will still take care of their young. But not all biological mothers are warm and loving, there are some who hate children. Kill them while their still in the womb. Abandon them while their still an infant or simply care for them just so nobody would talk bad about them. These women only want sex. There is also another kind of mother. A kind which mostly consists of women with good hearts.
Adoptive mothers are women willing to take care of children who they didn't give birth to. Adoptive mothers don't have to adopt a child, but they are willing to sacrifice time, money, etc in order for the child's present and future. These women must have a big heart. But there are women who are forced to adopt a child due to legal matters. While some of them are kind, other are cruel.
Most stepmothers like in fairy tales are cruel. I don't know about stepmothers in foreign lands, but in my country, most stepmothers are cruel. I know a person whose father had remarried after that person's mother had died, that person's stepmother treated her very badly. She would burn that person clothing and do all sorts of cruel things.
In the end, the definition of a mothers widely depends on people's perception. A person can always think of their aunt as their mother. Just like beauty, definition is also in eye of the beholder. Thank you for reading and have a nice day.
