Whats different from Home?

So this is going to be an ongoing list but as I notice things here that are different from home I will try to update the list (also its in no particular order)...

1. The public transportation system here is far more vast and accessible
2. Groceries are incredibly cheap (try around $30 for a week of good food)
3. Cars are smaller (gas is far, far more expensive)
4. Cars are also nicer 
5. People often put car seats in the front passenger seat
6. Cell phone calling plans are far less expensive
7. Emergency vehicles make a different siren noise (this I will never understand)
8. People pay attention to the crosswalk signs and only cross when they are suppose to
9. Nowhere is air-conditioned (took me a heat wave to realize how much I miss it)
10. You never get a bag at the grocery store
11. People drive very fast, especially taxis
12. EVERYTHING is closed on Sundays, except some restaurants 
13. We really need to switch to the metric system
14. Strangers stand/sit closer together on public transportation
15. There are deposits on everything- shopping carts and drink glasses to name a few
16. At the end of class everyone knocks on their desk as a sort of applause
17. People are Generally more dressed up, you don't see people out in sweatpants for the most part

...and I will continue to update the list as I think of more
