Difference

I started teaching my 6-year-old daughter “who is a boy and who is a girl”. It is a little confusing in Europe to recognize the difference between girls & boys because they both remain in almost the same get-up. So I tell her that the boy is a guy who has short hair and wears a t-shirt with jeans. whereas a girl is somebody who has long hair and wears a long shirt. Was she confused? One day while going to school we saw a man with long hair wearing a T-shirt and then my daughter mentioned to me “Mama, she is a girl” I cleared her “No, he is a boy as he has also a beard on his face and some male can have beard or mustaches on their face too” then we spot a female with little hairs wearing a t-shirt and my kid said “mama, that one is a boy” I confirmed her “no, she is not a boy she is a girl as her t-shirt is like a females t-shirt”. How do I comprehend more differences? After that, I cleared her some more differences and looks about masculine...
