My niece is the boss!!

Today I took my nieces who are 7 and 8 years old to a park near our house I let them play and I sat down on a bench playing on my phone after like 15 minutes I went to check on them and from far away I heard my 8 year old niece scolding a boy who looked 10-11 from what I understood and heard is that he threw a bottle on the floor and she was scolding him for not throwing it in the trash can? 😂 From what I heard her say: what's a trash can for ? I will teach you how to use it (she took the bottle and threw it in the trash can then came to me ) I was like omg!!! This is exactly what I did to her when she threw a piece of paper on the floor few months before 😂
