A non-verbal knucklehead learns

In the past week or so, I realized I was misreading some of the non-verbal cues from the fine folk of Bien Hoa. The easy one: The peace sign means hello; westerners wave their hand to say hi. Next, when the Vietnamese shake their hand quickly back and forth (with no arm movement), that means "no" or "we don't have what you want." I thought it meant "maybe" or "don't know." This misunderstanding caused me more than a little grief and confusion. Finally, when the middle-aged males gave me the stare, I thought it was alpha-male, machismo, smack-down time. Wrong again. When I got the stare a couple times this past week, I politely bowed my head and smiled, and they responded in kind. I wish I figured this out earlier. They just wanted to see how the visitor treats others. Got it.
I've developed a hideous rash on my face from a motorbike helmet chinstrap. I've got medicine, but the heat and my sweating keeps the rash thriving. It features blisters and swelling welts. Lovely. Welcome to the tropics. I'm growing a beard to cover it.
Also got a stomach thing. It's not as bad as the ones I got in Peru, but it's got my attention. Oddly, with a frightful face and grinding gut, I had a wonderful week of classes.  Students were great (and probably intimidated by my Frankenface) and the lessons went really well. Go figure.
My apartment is a little like Animal Planet, which I watch every night on the apartment's wonderful flat-screen TV. I've seen  a couple generations of geckos come and go. I watch them mature from little babies to full-fledged lizards. They play in my trash, run all over the walls, and hide behind the pictures on the walls and under the throw rugs. They keep the roaches and mosquitoes at bay. Nature is so beautiful.
Finally, I broke my vow and bought a motorbike Thursday. I got tired of walking everywhere and arriving a sweaty mess, and I needed some freedom of movement. My two favorite coffee/smoothie spots near my house are gone. One closed and moved. The other one burned down. Now I've got mobility to find a new coffee spot where I can sit and watch the motorbikes go by. The traffic is wild and comes at you from every direction, and you trade paint with the bikes alongside you. But if you take it slow and are really careful .... you'll probably still get smashed. Screw it.
