wake up
My father-in-law's bad habit is he always going against what other people say. If you state a fact, he will go "how can?". Hey, it's so irritating whenever he does that. As if he is the smartest person on earth and Mr.Know-It-All. Whatever you say, he will go "how can?" How irritating!! The world has changed. It does not matter whether you've eaten more salt than us.
