I don't have any friends where I live now, in Canada. I took a job that pays a lot. Technically I have 5 friends from school, but I see them once in a year at most. Really there are 3 that I have seen in the past year. And even then, there is 1 that I have a lot in common with. We play video games and watch some cartoons. But I don't have any friends who would go to conventions.
When I go to cons I meet people who like cartoons as much as I do. It's nice to know those people exist but I wish I had some friends near me.
