Going to American grocery stores and seeing all the weird warnings on dairy. I remember thinking how can I feed this to my kids when they have warnings that they drug their cows in ways that are illegal in most other countries, because they figure it "doesn't pose any significant risk," then trying to find healthy alternatives but discovering the ingredients in their items are different from the stuff from the same brands back home. I found grocery shopping crazy there. Also, the warnings that everything could totally, possibly cause cancer, like "this parking garage has substances known by the State of California to possibly, maybe, I don't know, kill you over time," or something like that. Graffiti and mess in the public toilets was also a culture shock.

Ireland having two separate taps for hot and cold. How do I wash my face with that? A scalding stream and an ice cold stream. No, I'm not filling the sink because ew.

Cuba, bless them, with their toilet paper garbage cans because you don't flush the toilet paper. Also, pubic toilets often not even having a toilet seat. Why? Just why? I mean, these toilets come from the factories with seats on them. You have to choose to the remove them.

Clearly I'm easily shocked. The world is full of strange things.

Just thought of another, yes, tied with the previous three for my top moment. Norway you just walk in front of cars. They stop for you. That's called a suicide attempt the rest of the world over, but in Norway, if they see you attempting to cross at the zebra crossing, they will stop for you. It's hard to get used to when you feel that vehicles should have the right of way.
