If a man sends a note in nostr, but no relay gets it, did the event even happen?

nostr:npub1qny3tkh0acurzla8x3zy4nhrjz5zd8l9sy9jys09umwng00manysew95gx I guess I owe you an apology, man. I thought you muted me somehow for repeatedly asking for the title song of your podcast, but it seems it's relay shit.

The not so funny thing is that I can only see your response on snort, not on any other client. I can't even see most of the replies from others.... It's really confusing whatever is going on.
