How do sisters usually send text messages to flirt with boyfriends?

When is the most effective trick? "Guest, do you need special service?" No matter what happens, he will cheer up and treat you well. Sometimes when eating papaya, he said, "I'm eating papaya, which grows NN", and then said, "Buy a cucumber at night and grow JJ." What's more, I always make two eggs for breakfast, and then say, "These two look good, but they don't seem as good as BF's", and then he is a spirit or something.
