No, your not being a bad friend. You're just making the most of what you've got, as opposed to mucking up something that's already been delivered to you on a silver platter. And sooner or later everyone gets good at that. (And they're the ones that smart.)
The key is just to keep making opportunities when you can. Sometimes I get frustrated when my entreaties are ignored, but then I just have to pick up and keep on keeping on.
