One thing I hate about a long day of walking the city streets of Buenos Aires, is that I know eventually I'll be sticking my armpit in some random person's face.  This is because  my current mode of transportation is either a cramped subway train or a crowded city bus. This isn't as big a deal to me, but I'm worried about that random person I'm standing in front of.  I'm basically putting my musky armpit in their face.  Personal boundaries out the window.  


Maybe I need to change brands of deodorant "to be Sure".
