Spying Friends

So... if I found out that one of my close friends was spying on me, at first I'm pretty sure I'd feel betrayed. But who wouldn't? Then, after the initial shock and bewilderment passed, I'd ask myself why? Why would one of my friends want to spy on me? Is it because they're looking out for me? Just trying to help me out? Or is it to find out who I hang out with? What I do on my free time? Plotting to kill me? Ha - If I found they were doing it in my interests, say to prevent me from getting hurt or something along those lines, I think I could forgive them. I mean, it still isn't right but, I would respect and appreciate what they were trying to do. The thing is, if I didn't know why, I shouldn't assume that it's to hurt me. I mean, like most anybody, I probably would assume the worst just in case but the optimism in me would want to believe a close friend would have a very defensible, good reason for doing it. On the other hand, if I found out it was happening because they wanted to get to me, say injure a family member or do something bad to another friend, I'd be pissed. Most likely, I'd spy on the back - find out why they'd want to do such a thing. Also, when talking to them, I'd drop subtle hints implying that I know and see how the react and try and find out more about their motives. At the end of the day, I'd probably just feel baffled and sad, with a lot of anger mixed in.
