Learning a foreign language
This can be totally fun gathering nouns and verbs and constructing simply sentences. Don't kid yourself everyone you meet on your travels appreciates your effort. I once carried a conversation in Italian with a porter for 15 minutes telling him about my grandparents migration from Italy as we traveled from Rome to Florence. He was so pleased meeting me he refused to take my tip when he assisted me with my luggage. Instead he said with a big smile "piacere mio!" which means; It was my pleasure!
