What do you say to a girl who is laying on the floor, beaten and with swollen eyes? Nothing, you shouldn't have to say it twice.
Why wouldn't you want to say it twice?
It means that if they are laying on the floor beaten half to death they probably don't want a conversation.
People who are being beaten are going through a hard time and it is not okay to joke about. Making light about it by joking about them having swollen eyes can be hurtful, just like you would be hurt if people made a joke about something that caused you pain.
