Are you a sports fan? Do you watch or participate? Which ones?
My family has many interests . . . movies, music, politics and . . . BASKETBALL. First my oldest son played in high school and in 3-on-3's. Now he coaches youth competitive traveling teams as well as a college team. All three grandsons play at their schools, 3-on-3's and/or on the traveling teams. My youngest son has played in 3-on-3's and the local men's league. They wear basketball themed clothing, watch basketball, practice basketball and talk basketball. I worked it out one day and I have basically been watching basketball for more than 25 years.
I still don't understand the language or rules but I watch and I cheer.
