I Want To Talk About Parenting

So I behave with my aunts. But her daughter, my cousin was pouting when I didn't granted her wish. It is tiring. But I need to console my cousin. I am 20 and she will become 12 soon. I think it is one of my responsibility to lead and guide her. Because I am her sister. Thus, I have to manage her kindly. Maybe I am ready to get married because I am ready to face the little gurls tantrum. Yeah, I am facing it.
Maturity comes slow ,but when it comes you became wise
