We call ourselves frogs, my husband and I. It all started with the international symbol for TCKs (Third Culture Kids). That symbol is a blue circle that overlaps a yellow circle with green between. Kermit the Frog used to sing, “It’s not that easy being green. . . ” That led us to think of frogs. They are green and can live on land or in the water.
Personally, I don’t think it is only TCKs who feel they are a blend of cultures, not really one or another.
We tell people we are from our passport country. But just get us back there for a week and we see just how much we are like our host country. Some of the customs, thought patterns, and life-style of both places have gotten all mixed up in us.
