it's not a controversial take to say a message's tone affects how it's taken. could you explain why it's so difficult for you to hear the request "could you be nice"?

or do you genuinely believe a message's tone doesn't affect how it's received? because if so, i've been wasting a lot of effort on being nice to you, myself :p (that's a joking tone, because it's almost certainly not going to be obvious)
