How does it feel to have someone have a crush on you anon?

A girl had a crush on me in highschool but she was ugly so i just ghosted her.
(didnt want to be rude)

as far as i know thats all
its times when i look back and reflect on things that happened to me I realize what people were doing/hinting.

I think got chased by a girl in college, but i was trying to get upstairs to my destination and maybe she thought "oh the stairs may be quicker". But before that she held the door open for me and complimented me as i walked into the building. She looked like she wanted a conversation with me.
