In one game, my character was inundated in friends; in my current one, it’s difficult to find two. Is it just the luck of the draw, on when friends show up?
New friends who aren’t associated with existing ones come out of the woodwork when you go out somewhere, like shopping, jogging or evening classes. They are more likely to appear when you are happy, so watch a comedy show or read something cheerful
Also, there is a limit to how many new friends you can make in the same job, plus some jobs are much more sociable and involve meeting new people than others.
