— Hi there, John! How are you doing?
— I'm fine, but I feel like something bad is going to happen today.
— Why do you think so?
— I saw a black cat this morning.
— Haha, John, come on! Do you really believe in superstitions?
— Yeah. I am a very superstitious person. I think that some superstitions may be useful and sometimes really mean something bad or good. Anyway, you can never know if they are real or not.
— I prefer not to believe them. Life is way simpler if you don't mind about any superstitious things. I am not scared of black cats like you.
— But you can never find a four-leaf clover.
