I'm an only child, and very comfortable in my own skin, in my own company. However, I have learned that at about the five-month stage, I get really tired of being a Gringo in Latin America. The language barrier, the repetition of predictable interactions, the repetition of each day's routines really start to get on my nerves. Coming up on my sixth month on the road (much of it shared with other people), and I actively want my trip to be over. It's hard to determine whether it is just me, or objectively the environment. Since I left Argentina, each country has been less inviting, less engaging, and more apt to annoy me.
