Rationing mugicha, and learning to walk

Rules about what could be brought on board were very strict.  Food needed to be single serving packets, and resealable.  I was able to bring on the mugicha (barley tea) that Dan and Mary Beth gave me as a farewell gift.  As the only other tea apparently available is caffeinated Lipton, I am trying to make this last until the ship gets to Japan.  The coffee drinkers wish they were making their own.  There is infinite tea water at the coffee stand.

I should have paid more attention in Japan to the various opportunities to learn to stand and walk on a moving bus.  That would have clearly helped prepare me for standing and walking on the moving ship.
