This is a dumb question. Sorry. It is. Either it costs more to buy things or it doesn't. Either you're rich enough that it doesn't matter or you're not
Here are the answers:
1) I am an American who travels overseas. But I am rich so I don't care.
2) I am an American who travels overseas. I am poor, so it hurts.
3) I am a foreigner with a strong currency who travels to the U.S. So it helps.
4) I don't travel abroad/I don't understand currency/my currency is pegged to the dollar/I have no idea what you mean
Please improve.
