You were late, you lost interest of someone who's effectively a complete stranger, you lost it before it even started.
Since you lost it to what you consider unfortunate circumstances then you should be able to brush it off and try to make another effort later but without such issues coming up.
Oh, I see. I'll be sure to extend the same heavy handed, dehumanizing standards to everyone else from now on. Being late is worse than not even showing up at all, without any notice! I sure am in the wrong here.
But I think I'll take your advice. Here's something I can assert, end this frustratingly one sided conversation by opting out. Here's something else I can do: stop treating people with the same respect and basic dignity I expect to be offered to me, regardless of how well I know them. You really set me straight, thanks for that.
Yes and no.
You expect too much respect and dignity from strangers and that's self-destructive. Once you've actually established face-to-face communication, then you can earn respect and act dignified.
And this isn't a conversation. You have failed at your task and I am telling you what you did wrong and what you need to do. There's no back and forth here, you're just being given sorely needed advice for your failure on a hookup site. ---
