Whenever traveling we only highlight the good parts and fun times. I'm a realist, and I know that traveling can be dirty, exhausting and downright not fun. But that's the best part of it. You learn more about yourself in those times...and about others. When we were Edinburgh I told a twelve-year-old to F off. I know, I know it's horrible. Not my finest moment, but he was a street urchin and cussing us out, and I had had enough. I'm not proud of myself, but in that moment I learned what my limits were and that I can really disappoint myself sometimes.
So being a realist I know there will be times when we'll see ugly things, get annoyed with each other, and may be disappointed.
