I love the idea of needing a translator for standard American English to Pidgin English, but if our words are not in common use then they wouldn't make any more sense to Nigerians than "foil" for fuel. Also, with the milk, you really make clear the downfalls of lacking context for context-specific things.

So many handsome people in these photos. I think Nigeria has that reputation, though you'd probably have a better sense by now of whether it's true (depending upon where else in Africa you've traveled).

Good luck as you continue on, and make sure your luggage is by your side now. ;)
