kitmill,
I've always been on one project or another but on some Saturday nights I did feel that things that were happenin' we're far from me. Today, I live with my girlfriend (since about 8 years). I've always been happy to be alone and happy to be with someone. There's a good and a bad side to everything. BUT, I was wrong all the time to feel alone on some Saturday nights. Some Saturday nights, we go for a stupid video with beer and pizza...like I'd end up doing when I was single...
So, moral? You want fun? You make it yourself! If you're feeling lonely alone, you'll feel alone with your friends too.
