@alexsdu Well yeah, if the person you asked out is a total bitch/asshole that can happen, but you can always respond to harassment with "Yeah I asked them out, but they weren't interested, so I won't bother them again," and a shrug. It's hard for bullies to keep up harassment with a response like that.
And on the flip side, sometimes you get something wonderful like what happened to a friend of mine. He asked a girl out at work asa she was heading home and she told him she had a boyfriend. No big deal, right? Well about 15 minutes later she called him at work to apologize for being so abrupt, and told him he was a great guy that she'd have been honored to go out with if she wasn't already taken. He still remembers it as one of the best days of his life,
even though he got turned down.
Not everyone's awful, even in high school.
