Ideas

Why do I always seem to get the most ideas when I don't have enough time to write these ideas and work on developing them? I've got an idea that I think would be a lot of fun, but it's hard to actually have time to do it! I'd planned to work during soccer tonight (while I sat in the car), but it's been cancelled and the kids are driving us crazy already! If I try to write, they have a million and one questions and interrupt and I lose my train of thought and AAAAAGGHHH!!!!
