Totally! My uncle taught me to change a tire once and we still talk about it. That shared focus, even on a small thing, builds its own little world. It's less about the task and more about being in it together.
But is learning an app together really that deep? It's just a tool. My generation and my niece's are totally different worlds. Sharing clips is cool, but that's a pretty thin thread to hang a real connection on. It takes way more than that to actually get each other.
