If you can speak English, you can travel in Germany without inconvenience.
My several friends gave me advice.
I had believed.
I wrote e-mail of a reservation of a hotel in English.
But an answer came in German.
I purchased an electronic dictionary before a trip in a hurry.
There was the person who cannot speak English even in association of sightseeing.
I lost my way there.
I asked several Germans how to get to Hamburg Airport in English.
Nobody speaked English , even a simple word of "the right" and
"the left" .
We communicated with signs and gestures.
But I was lucky.
One woman took me to the entrance of an expressway.
I felt regret.
I thought I should study German !
