what have you learn about washington d.c.??

when i was in Washington D.C. i learnt a lot of things. from now on i know that all prejudices that french peoples have on american people are wrong.American people are very very nice,generous, welcoming,they have them heart on their sleeves...
Before the trip i thought that they had a superficial life,i mean,i thought that for exemple the food was totally chemical,all the teenagers was spoiled,only children,selfish but i was surprised to see the totally reverse.
American students were delightful and very dedicated to us like teachers(mrs foxen......)headmasters and parents.
Life in America ismore exiting than the French life because i think that American people are more open than fench people.
