Running into some problems

I was supposed to start filming today, but my friend who was supposed to act in the film canceled last minute. I was excited and had everything ready and then this happened! I'll start filming this week, thankfully I still have time. I have learned that I should talk to more dependent people and people who are surely to come through with set dates. Also, I've learned that thankfully since I started early this set back won't be a huge problem.
