Atrue friend would never put you in danger or ask you to do something with which you are not comfortable.

I believe true friend will tell you things or ask you things even if it will make you uncomfortable as long as it will do you good in the future or save you from embarrassment.  True friends never hides their identity from you and is never afraid to tell you the truth.

Currently, as of february 2016, an american traveling in france would be by the exchange rate. the weakness of the euro and the strength of the us dollar means that items in france cost less to an american than they otherwise would. of course, if this trend reverses and the us dollar weakens and the euro strengthens, such as was happening in early 2008, an american traveling in france would have an adverse experience because items would cost relatively more.
