Thinking back, I realize for nearly all of my life, I've not had anyone ask about my day. When I'm done with work, I return home to solitude, never telling a story or sharing a frustration or laugh. Most of the time I don't think of that as especially lonely. It's just the way it's been, but I suppose it's not that way for most.
So at 32, I'm just beginning to learn how to talk about my day, though I can scarcely imagine why anyone would be interested at all. Couldn't even guess how many other normal social interactions and conventions I've missed. Maybe I'll pick things up as I go.
