So many of my favorite travel stories come from Africa. I'll never forget the crammed bus ride from the border of DRC to Kigali, packed full, me wedged in after an overnight hike to Mt. Nyiragongo. Sweaty, stinky, exhausted and sore when the woman sitting next to me politely asked "can I" and pointed to my shoulder. "Yes," followed by her taking a nap on my shoulder.

30 minutes later she woke up, said "thank you," and we never spoke again. Just two travelers, trying to get to the destination as comfortably as we could.
