This is a good post.
I think snooping can become addictive in and of itself. It's one of those things that I find once I start- I cannot stop. I usually don't until I find something questionable and then I am backing to feeling like crap again.
Even before I knew the issue was drugs I use to snoop because some things just seemed "off" at times. Even then if I found something - what did I do with the information besides freak out and induce drama. So I have since adopted the habit of - I will not looking for anything I do not want to find. Despite this- I have still looked through his backpack,cell phone etc. I am an expert detective when I want to be- but all the previous posts are dead on when they say - Look, but decided prior whether or not you find something- what you will do and be prepared to follow through with it.
I am still stuck on this part- snagged at the "following through."
