Paranoia

So, as you all know, I had my cell phone - actually, my aunt's really-really-super-duper-expensive-and-not-at-all-worth-the-money cell phone - stolen by a pick pocket the other day. Today, on the bus back from dance class, I started thinking about the evening when it went missing and I realized when it happened, who did it and how he did it. That bastard.
So the events went like this. I keep the cell phone with my bus pass in a pocket on the front of my purse. I get on the bus and open the pocket to pull out my pass and as I'm doing so, a man gets off the bus and jostles me in the process. I'm pretty positive that in that moment, he reached in the open pocket, grabbed the phone and then got off the bus. That bastard.
I got home last night really late because Anita (my supervisor) is leaving the office. We had a big farewell dinner at a Korean barbecue place and then went Karaoke-ing at a tacky place somewhere nearby. It was fun - our coworkers and bosses are super scary and not at all what I expected when they are singing. LiQiang in particular creeped me out. He's normally such a nice boy...
After we finished singing at around 1:30, the office secretary, WangJing, drives me part of the way home and drops me off somewhere nearby where I live. I was standing on the corner hailing for a cab when a red cab approaches with two men in it. It looks like the meter is running so I take a glance inside. Upon looking in I see there's two middle aged men. One's in the cab seat and the other one is in the passanger seat. They both ask me where I'm going and I was polite saying that I'm fine, I'll catch my own cab, but thanks all the same.
Some things wrong with this scenario:
1) Obviously I'm slightly paranoid because there aren't that many good samaritans in the city of Shanghai.
2) From my experience, cab drivers are completely disinterested in their passangers. This one seemed a little too buddy buddy with the passanger, even offering a bit to the conversation (aka Get in the cab, lady).
3) If a cab driver had a passanger who wanted to be nice and help a stranded lady in the middle of the night, he'd probably say no, because that would mean less money for him or one of his fellow coworkers.
Looking back on it, I also noticed a couple of things:
1) A similar thing happened on Wednesday night when I was hailing a cab. Except the taxi didn't stop on the corner, rather the passanger rolled down the window while the car was passing and put his arm out in a follow-me gesture. Yah, like hell I'll follow you.
2) I really wished I bothered to copy down the cab driver's ID number so I could report a possible hobby rapist who spends gas money entertaining his friend and trying to pick up daft foreign girls for god knows what reason instead of doing his job.
So yes, I'm feeling very paranoid in this city right now. I start to wonder if everyone who takes a second glance at me is a pickpocket sizing up my worth or a horny guy thinking about luring me into a back ally. My coworkers told me not to discount children for thieves, so now even little girls in pretty pretty princess dressed are treated with suspicion. Every middle-of-the-night-cab driver is now a possible mugger who might drive me out of the city and put a bag over my head before beating me and taking all my stuff. Bastards, all of them. I wish I had something like pepper-spray or a knife, or something. I get horrible images in my mind about all sorts of things. What if I had gotten close to the car and they had chloroform? What if they had just jumped out and grabbed me? Sometimes I wish mom had let me take those martial art classes in Chinese school...
