A Chinese old saying goes, a kind of rice fed a thousand kinds of people. We can't possibly expect other people to behave how we wished them for.
One thing I noticed, the guy who always asks for information and then no show. I get that a lot 🤣 they invite themselves, but they didn't turn up, it's the exact opposite of party crasher.
I can't recall the last time I said I was going to something and then didn't go. I am one of those people that if someone invites me to something and I dont want to go I'll just tell them that.
