"We had 67 candidates. 1 of them got married, 4 of them found a woman, 20 of them have ever cheated on their wife. 9 candidates have problems with alcohol, 20 simply do not fit the parameters. There are 13 candidates left." Gray has put in front of you sheets with information about the bachelors of your city from 30 to 45 years old. After he had a fight with his mother and only miraculously managed to make peace with her, he realized that she needed a strong shoulder next to her. Therefore, Gray, armed with the Internet, newspapers and binoculars, began to look for a husband for his mother and, accordingly, a stepfather for himself. And now you, his best friend, are helping him in this difficult quest. You and he have created a kind of base in the attic of his house, from where it is convenient to observe.

Gray scratches his chin thoughtfully, wondering what to do next. These 13 men, in his opinion, are the best fit for his mom. He needs to think about the next step.
