Teacher crushes?!

Yassy • I`m 14 and the biggest feminist ever.... no need for guys here
Ok so, im in yr 9 and i have the biggest crush on the librarian aka the yr 8 math teacher. ... he's 25 and I'm 15.... am I the only one who has or had a crush on one of my high school teachers? I told one of my closest friends and she just laughed at me and now every time he passes she looks at me, i try not to make it too obvious (which works) but my friend makes me feel stupid for liking him. Am i the only one who has a crush one who has a crush on a teacher? Because tbh i feel a bit crazy loving someone that might teach me.
