Enquanto você espera, você vai com seu _crush_ :heart_eyes: e pega uma mesa, senta e conversa com seu _crush_ :heart_eyes: por um bom tempo (como seus hambúrgueres são muito saborosos, leva um tempo para serem preparados).

Enquanto você está sentado na mesa com seu _crush_ :heart_eyes:, esperando os hambúrgueres, você pode gastar o tempo admirando como lindo, maravilhoso e esperto é seu _crush_ :heart_eyes:.

Pendant que vous êtes assis à table, en attendant que les burgers 🍔 soient prêts, vous pouvez passer ce temps à admirer à quel point votre crush 😍 est géniale, mignonne et intelligente ✨😍✨.
