There is a girl I like at work, but I don't know how to say hi to her, sometimes I see her up close or from a distance, but I don't always say hi to her because I think I would look like a simp. She and I have rarely spoken, and that's why I don't feel confident saying hi to her. In fact, most of the times we've said hi to each other it's because she's told me so. I am shy and introverted. Can anybody tell me what I can do?
