Reverse Culture Shock?

Some lists during our Stateside stay:

Pleasant surprises:
* Being able to get out of either side when parked
* Understanding 100% of a radio or TV program
* Grass (lots of it, in front of almost every house!)
* Trees (with beautiful colored leaves to boot)
* Banana cream pie
* Clothing sizes that fit
* Parking in front of a store, instead of on top

Oddities:
* Self-checkout at the grocery store (when did that start?)
* Machines are strangely quiet (nearly everything from the gas pump to the escalator talks to you in Japan)
* Drink sizes, serving sizes and people are strangely large (possible correlation here)
* Foods are incredibly sweet, salty or fatty (much more so than I seem to remember)
* No bicycles or motopeds on the streets!
* Television programming increasingly unfit for most human life
* Thousands of choices for just about everything

Caught myself doing:
* Saying sorry to someone I bumped into...in Japanese by mistake (that got me an odd look)
* Standing in front of a store waiting for the door to open (Japan is the land of automatic doors)
* Getting in the front passenger seat and preparing to drive...and wondering why the steering wheel was gone (its on the right in Japan)
* Driving on the wrong side of the road (just briefly, mind you)
* Gaping at the aisles of cereal and snacks
* Wondering why US currency suddenly looks like monopoly money
