Persimmons. I know they're available at least in the bay area because I had them when I lived there briefly, but have never found them in my regular home in the pacific northwest. I also don't remember them as a kid growing up in Tennessee.
No, but my oldest son(6) loves them. There used to be an olives stand at the farmer's market near us and we surprised them by bringing a toddler who wanted olives. We let him try a bunch of different kinds. I will eat olives if I'm drunk and someone gives me a slice of pizza that has them, but otherwise they're a no for me.
I feel like it's similar to social media, but serves a different purpose at least in my use of it. With social media sites like Facebook and Instagram I'm mostly interacting with people I know in real life. To me it seems closer to Youtube, because for both of those it connects me more to larger cultural or artistic things, rather than what's going on with my friends.
Thank you! Yes, ARFID has been on my radar since learning one of my friends has it and I'm curious if my son has it as well. I've definitely been guilty of not hiding my excitement when he tries a new food, so that's a helpful note.
