Jason

Your name is Maria. You come from a wealthy family, and your parents have a lot of friends, so they decided to gather four families in a rented house by the sea. First, you arrived, then one family of friends, the Olivier family. There were three of them: mother, father, and son Jason, an unpleasant person, as you thought.
Next came the 2nd Jenson family. There were only two of them, Miss Olivia and Mr. Michael. Then another friendly 3rd family arrived, my favorite because my best friend was there, her name was Margot, her mom and dad were very sweet, her dad was Alex and her mother was Monica. The 4th family included Miss Fiona, Mr. Marius, and their 10-year-old son Ivan.
You and Margo were 18 years old and in 11th grade, you lived in the same city, so you were so close.
All the families were rich, you came for a whole month to have a good swim.
When all the families arrived, you decided to get together in the evening and have dinner.
