DH thinks that under no circumstances should you let anyone who phones up think that they are interrupting you. Even if we have just started eating a hot meal and a member of his family phones, he will not mention that we are eating, and chat to them for up to half an hour, whilst his dinner goes cold.
I however have no qualms about just saying politely 'I'm really sorry but we're just in the middle of tea, can I call you back in minutes.' DH thinks this will offend people.
So AIBU?
