SE Asia is the place to be if you want to conquer your fear of the dirty. I didn't used to handle icky things. Here, it's no problem to pick your nose in public, and the 'farmer blow' is an acceptable thing to do in the middle of the sidewalk, at the beach, into the sink where you wash dishes at the restaurant. Yesterday I came around a corner to find a woman with her finger up her nose. Had the situation been reversed, I would have pretended I was just scratching, but she just left her finger up there, nodded, smiled at me and kept digging.
Over the last three days I have:
Put my backpack on the dirty dirty ground.
Picked up that backpack and put it on my back.
Put a very used bus blanket and pillow against my skin.
Washed my clothes in the sink and dried them on the beach.
Peed in a men's urinal.
And right now I am laying on the hotel blanket. I can smell my armpits. I just traveled for twelve hours on a disgusting bus and now I'm at the hotel. In the past I might have run to the shower and not touched anything until I was clean, but here I am, chilling on the blanket that never gets washed.
I have a feeling if a gecko ran up my leg I would just calmly brush it off.
