Two Gentlemen of Verona

After 5 months, I am still surprised by the manners of men outside the US.  I can't even narrow it down to European men or South American men.  Dutch, Brazilian, Indian, German, and to a lesser extent British and the one Greek guy who spent several years in NYC, all have more manners than 90% of the men I've encountered in back home.  On two separate occasions today my male friends took public transport in the opposite direction of their homes just to see me to my door.  I've also had classmates pick up my empty dishes at lunch because they were heading in the direction of the kitchen.  They pause before going through doorways to let a woman go first.  It caused a great deal of confusion in the first few months, I ended up playing many games of "you first",  "no, you first", "no, please, I insist".  Should I get used to this, it will be a sad day if I ever have to convert back.
