Traveling in a third-world country is the closest thing there is to being married and raising kids. You have glorious hikes and perfect days on the beach. You go on adventures you would never try, or enjoy, alone. But you also can't get away from each other. Everything is unfamiliar. Money is tight or you get robbed. Someone gets sick or sunburned. You get bored. It is harder than you expected, but you are glad you didn't just sit home.
