Problem of Theft

While in US, I was so used to keeping valuables around the house (including cash) and that has costed me dearly here. In US, even when we had cleaning maid come in, the cash was never touched. Many a time we had things outside of our house (like the office bag with laptop) or kids bikes all night and were never stolen. However it is amazing to see what people steal here and how. I have in the 3 months lost 3 mobile phones (costing around $400 total), a Ray-ban glasses ($70) and had it happen inside the house!! We naturally suspected the house maid and filed a police complaint. When you buy a phone here, it comes with insurance but claiming that is such a hassle I have not bothered to claim the insurance money. The police came and took her to the station and questioned her and she kept to her guns of being innocent. Obviously I did not have the heart to proceed further due to lack of proof and asked the Police to let her go. I felt really sick that day thinking, what if she had been really innocent and I made her go through the agony. Since then, we have become extra careful and follow the housemaid every step of the way, which is a huge waste of our time. Recently, like everyday, we kept the trash can near the gate for the trash lady to pick it up. However that day she instead of keeping it back inside the gate left it outside. The trash can disappeared in no time. Because we live in a very established neighborhood, these things are relatively infrequent. I can only imagine what it is like if you live in one of these upcoming layouts. People here have lost all sense of morals. The lesson, watch your back and trust no one unless you really know them. The problem with theft is more than financial loss, it kind of hurts you that somebody invaded your privacy and that is a problem hard to reconcile.
