You're obviously not a woman who has had to deal with potentially threatening people in your love life. Among women ghosting is 100% a legitimate way to refuse a second/third/etc. date. In business, companies routinely ghost candidates they're not interested in because of the hassle and risk in interacting with candidates who are clearly no-hires. You don't owe anyone with whom you do not have a solid established relationship an interaction.

It's a word we need to stop using. Along with "Flexing".

I had this one English teacher who squashed any interest in writing after I took his class. He was known as Red because that's what color our papers were when he was finished grading them.

He did say a few thing that felt right. One was just don't use cliches. The other was don't use slang.

I have never met a single person in my life who didn't ghost multiple people especially in business and dating. Like I receive 10 messages from LinkedIn everyday from recruiters trying to hire me when I'm not on the job market and trying to focus on my job and hobbies. What am I supposed to do?

It's clearly rude to ghost friends, acquaintances, business partners etc. But if someone reached out to you with the intention of doing business with you, I think it's ok to ghost them if you're 100% not interested. Am I wrong?
