The girl on the way to school

This is just a random post about this girl I see every morning on my way to the bus stop. She's about 12 and has a little brother who is literally tiny but must be about 8?? Anyway I see them every morning and she generally does look like an evil child, she walks ahead of her little brother completely ignoring him and he wears this massive backpack that's literally bigger than him! I feel so sorry for him. Then one day when I was walking home I saw her leaning out the window from where they live holding a ice lolly or something and the little boy was outside on the grass shouting at her (I believe she had his lolly) then she threw it on the grass and he ran after it :(
Poor little guy.
