I trust my friends and a few neighbors here to some extent, but I wouldn't give them the keys to my home. I don't trust anyone else, and don't open my door to strangers. My MX neighbors do the same thing.
Mexicans don't trust each other either. Maybe it's a cultural thing. Has a cashier in any big supermarket or store ever had change available immediately if you handed them a 500 peso note for a 200 peso bill, without calling a supervisor for change? With labor as cheap as it is in MX, why do parking lots use automated machines to take your money instead of a live person? Management doesn't trust their own employees or potential thieves over a few thousand pesos in a drawer, why should I? My neighbors did as I did, and didn't answer much of the Census or IFE polls either.
Considering most of my neighbors have huge walls around their houses, security cameras, electric fencing and large dogs.... plus pay people to stand watch in front of their house...I am thinking they are not very trusting either. I've heard so many stories about the houses being robbed around me...most of the time security being in on the robbery.
