because of the interesting bathrooms here.  They are ceramic flushable holes, with two ceramic foot grids on either side.  We call them squatty potties.  Not sure if we're supposed to call them that...but we do.  We've all improved in our use of them...now that we've also figured out that we have to bring t.p. with us...ALWAYS.  The nicer malls have fairly clean squatties.  Most other places, they're pretty bad.  Not particularly dangerous(I wrote that for my mom) as your body doesn't touch any surfaces...just gross. 

So thus the evolution of the 'full bladder, bridge dread'. 

So anyhow...we headed over the bridge for TaiPing...
