If I were Paul.....
In that scene where Paul gets upset with his father and runs off and hears his mom with that Howard homewrecker guy, if I were Paul, I would have taken Howard's camera thing or whatever it was, threw it into the ocean, then either done one of two things:
1. "Accidentally" walked in on my mom
or
2. Gone and told my dad no matter how upset I was.
Or maybe I would have just gotten rid of Howard's camera and then run off and act innocent when I got back and made them think that some punk kid threw it in the ocean just to be mean.
