Talk to someone with a bad mouth, sweetheart.

A knife with a mouth full of tofu and a heart full of honey. People who are kind-hearted are generally straightforward, and people who talk sweet all day are often treacherous. I'd rather be friends with a straight-tempered person who can make you angry even if I argue with you all day, than with a wretched man who secretly calculates you like honey in his mouth all day.
