I love my uncle

At your pubescent age, your hormones are beginning to engage, causing you to undergo many varied emotional & disposition changes. Until adulthood, you may be unsettled to a degree. One day you may wake up & suddenly have no more sexy feelings for your uncle. Puberty can be a difficult, confusing time for some girls ; hopefully this period will be a blessing for you & not difficult.

Methinks this is called a crush.' There is a word for it. It is 'normal.'

Study hard. Do well in school!
