At the end of the 19th century it was a popular game on social events to answer a questionnaire. They should help to learn about the interviewee and their character. The French author Marcel Proust (1871-1922) was one of the most famous people who answered it (<a href="https://en.wikipedia.org/wiki/Proust_Questionnaire">Wikipedia</a>). This application allows to get a randomized question from questionnaire, e.g. the Proust questionnaire, so you can discuss it with another person.
