Do what I could through drawing wordless comics, keep a japanese/english dictionary on hand, hope at least one of my family members studied english, and call my cell phone to see if the other guy was revived in my body. if so, I'd hope he spoke english and see how we could get each other back to our own places. Meanwhile I'd find out where my cousin lived in Japan and have him try to help me.
WWYD if you had to choose between going to K con 2012 and the guarantee that you'd have your own house, laptop and stay-at-home job?
