When we’re speaking with someone on a mobile and the call loses signal, we can make it sound like it was the other person’s fault.
“Can you repeat yourself please, you just dropped out then”.
I know this seems minor and this could just be my own take, but given the awkwardness these moments create, I think it makes a difference to frame it as a neutral point.
“I’m sorry, I just missed what you said, the phone dropped out”.
