Calls are fine but I get irrationally annoyed about voice messages. I hate those!

Calls are still acceptable in most settings (and easily blocked if not) but I won’t turn on my speakers with strangers around.

I hate that how-to questions often are answered by some shitty YouTube video for the same reason (but even when alone I won’t watch your crappy 10 min video for something that could literally be answered by a single sentence).
