I found these two pieces online, explaining what it means to be German.
26 signs you were born and raised in Germany
9 American habits I lost when I moved to Germany
I would add a parenthetical title to the first article: (after 1980). There are few things on that list that are incomprensible to me (#2, 3, 16, & 23), but I've been in America since 1980. The rest of them are pretty spot on. The second article is an American's perspective, and boy did she nail it. Nicely done.
