Cultural Tip
In French celebrations, balloons (ballons) and paper streamers (serpentins) are classic decorations, especially for birthdays and fêtes de fin d'année. When buying them, you’ll often hear the term 'ballons gonflés à l'hélium' (helium‑filled balloons) and 'serpentins en papier' (paper streamers). Using the impersonal 'on' makes the request sound casual and inclusive, perfect for informal planning with friends or family.
