I don't think twice about someone getting on the bus with a live chicken, or a well dressed lady spitting on the sidewalk.
Kids are toilet trained a lot earlier here.
You see toddlers that can't walk yet being held in relief position with their special open ended pants unbuttoned doing their business in gutters, planters, etc. They are housebroken long before our kids are.
Kids start schooling a lot earlier here.
I'm teaching 4 year olds English, and I just added a three and a half year old girl to one of my classes.
People have sex a lot later here.
Most of the teens I teach here don't even date yet!
