I think as we get older, we step up more. It's sort of like our tolerance has a shorter measure. I think we see that even planting a seed is doing something.
She'll probably be back. It sounds like enough people are in on her secret that something will get done. The church and the police arent going to participate in her denial. I don't imagine your lodge wants squad cars outside three days a week either.
