I'm a 22 year old male in college studying computer engineering in the IT field and I have a crush on a teacher (not my teacher) who's in the medical field. She is every beautiful and I see her every now and then when I'm walking down the hall way. Every time I see her I get butterflies, I say hi to her sometimes but never know what to say to her. What should I do? Should I tell her that I have a crush on her or Just leave it alone?
