Some things I forgot about traveling to Australia:
1.  How long it takes to get over jet lag.
2.  How loud the wild and crazy birds can sound as they wake you in the morning.
3.  How friendly the people are.
4.  How many words have completely different meanings than what I'm used to.

What do you call the trunk of an automobile?
What do you call a school of K through 12?

What words are you aware of that mean different things between Australia and the U.S.A.?
