Everything in this poem is perfect! I can relate with the:

be polite and lady-like
never boyish or mean

Being part of the few girls in our class dominated by boys, I feel like there are always eyes that look in everything you do. Watching, judging. If you know how to use the tools they would say, "You're a girl! You should not be doing this!". It makes me feel like being a girl comes with a price.
