As a heavy introvert, I've started organizing small get-togethers with the help of my wife. I realized that, past a certain age, I was seeing my friends less and less. There are good friends I might see only once a year, when I did the math regarding life expectancy, I realized that if things continued on that path, I might see certain important people, at best, only another 30 or 35 times in total. So, at the start of the year, I decided to organize a monthly poker night and dinner with my inner circle, and to my surprise, everyone accepted. A few days ago, I ran into a former university classmate, I suggested he'd be welcome at my home for these gatherings, and his eyes lit up at the prospect. Another thing that caught my attention is that my female friends all have active social lives, whereas that is very rare among the men I know (again, past a certain age).
