Why should boys have all the fun?

Why are girls not treated equal to boys, despite whatever everyone says?
Like if i have to go for a movie with my friends, i need to be back by 8 while my brother goes at 8 in night.
If I have to attend a party, i need to wear traditional dress what my mother chooses, but my brother has his way out.
Granny favours my brother everytime.
My brother got a new bike last weekend, but I am being refused a scooty for past one month, and should i mention that my college is nearly 10km from my house while my brother's college is hardly a km or two away.
Why should boys have all the fun? Why aren't girl equal to boys?
