Your child/children make you talk a lot and they can get on your last nerve, but you have to be sensitive, kind and patient. In the end peace will be within and it is a good feeling.

Galatians 5:22-23. In contrast, the fruit of the Spirit is love, joy, peace, patience, kindness generosity, faithfulness, gentleness, self-control. Against such there is no law.

I believe if you are having a conversation with your child/children, and they use slang or their diction is wrong, you should correct them. Be gentle in your tone when correcting. Eloquence is important in most cases. There is a time and place for slang, jargon, vernacular or colloquial speech.  Remind your child/children if they write how they speak, they will fail English.

I wish you and yours a wonderful safe day.
