When I spent some time in the US in 96 I had a hard time getting the concept of Soda..I thought its like Soda Water, so I always declined and asked for a coke. That worked so fine that I just ordered coke from then on..until I spent some days with a Pepsi-family! LOL, I then went to drink Dr. Pepper...

In Bavaria where I come from we have some funny grammar usages. Most little villages are for example up on little hills...but when you go there you say "I am going down to the village" (or if it is in valley, you sometimes say "I am going up to the village")
