Help me out. We need a new term, and we missionary folks love discovering or creating words.

You knew exactly what I meant when I used the phrase “empty nest.” The chicks have launched and are on their own. “Empty nesters” are their parents.
Before I had nieces, I used to roll my eyes at aunts and uncles who went on and on about their nieces and nephews. Quietly I judged them as being pathetic and wanna-be parents. (I’m shooting straight with you, I’m not proud of the recesses of my heart and mind.)
And then my oldest niece was born. It took less than one day to turn me into the largest hypocrite on the planet. If Paul was the greatest sinner? I was the greatest eater-of-my-words. AND I DID NOT CARE. (Have I told you her latest antic? Would you like to see a photo? Can you even . . . can you?! She’s amazing.)
The time zones between us didn’t matter. The long plane rides when I could leave the field didn’t matter. Here’s what I learned—when love enters the picture, you don’t care what others think.
TCKs are the same. When you love them, really love them, they enter a category all their own in your heart.
This post and question isn’t just for singles. It’s for any adult. What I’m trying to put words to is about loving a kiddo who is not your child and who will one day grow up and move on to the next chapter in their lives.
The term “empty nester” rightly refers to the parents.
What word or phrase could we use for those of us who have a young person who’s been a part of our daily life and now they will not be? We will love them fiercely, cheer them on loudly, pray for them faithfully, and miss them dearly.
Whatever it is, that’s what I am. And I know I’m not alone.
