@e418317f Seems to me that if you feel the need to hide a second phone from the fam there are some issues afoot. 

 @d9095c4c I visited this museum some 20 years ago and thought it was very interesting. A volunteer, English-speaking guide showed us around. The exhibits clearly showed the arch of the centuries from feudal tribalism to now. I didn’t have to pretend like I knew anything. It was all very accessible for this gaijin.
