3CK
3CK refers to 'third culture kids' although some of us are no longer kids. It means people who have one or more nationalities, who don't live in the country of their first or second nationality, and live in another. They have another culture, neither their passport or birth country, nor the culture of the country in which they live. That's a third culture.
I'm a 3CK. When I was a teenager, I knew how old a girl had to be for carnal purposes, how old you had to be to get a drink, and what time you could get served in multiple jurisdictions. I have two passports, and have spent entirely too much of my life at Heathrow Terminal 2.
These days, it's milder. I put my Irish Passport on the counter and say 'buon giorno'. 'But you are Milanese'. No I'm Irish.
Then my twins put their passports on the counter with a giggle. Umm, Canadian. But you're a family. Si, nasciamo in Victoria, Columbia Britannica. But you're Venetians. I can hear it your accents.
He has to pass us.
We're 3CKs. We don't belong to any country. We're not owned.
