I keep noticing words that have two different meanings, depending on nwhich side of the Atlantic you live. Chips and pavemnet are examples.
In the US, chips are what we in the UK call crisps.
In the UK, chips are what you in the US call French Fries.
In the US, a pavement is what cars drive on.
In the UK, a pavement is what the pedestrians walk on (what you call a sidewalk).
For houses, what Americans call the First Floor is what we in the UK call the Ground Floor, with the First floor being the one above the ground floor.
As far as weather temperatures go, beware what scale you are using. The USA uses Fahrenheit; the rest of the world uses Celsius, and they are COMPLETELY different! 30 degrees i Europe is hot, and in the US it is cold.
Two contries divided by a single language, said Churchill, and he was right.
