"Oh my God, there is a naked woman in front of me, what do I do?"
* starts couting PI *
A good idea but I personally prefer the value of e.
Okay that is way above my pay grade. I can't remember pi beyond 3.14, and I can't remember the value for e at all. Hell I felt smart just remembering e was a mathematical constant.
There's a neat trick I use to remember 10 digits of pi by using a numpad.
After 3.14, you go up-right diagonal (159), then you do the up-right diagonal below that one (26), and finally you go left from there (54). 3.141592654 (rounded). Then again, 10 digits is not enough to last an entire shower session.
Even though Junna didn't look I wonder if Mayumi did, surprised that there wasn't any increased self-consciousness with the whole windowed shower setup.
