I've never been adept at determining others' intentions. It's rather difficult for me to know what others want. Other persons expectations are extremely confusing to me, to be perfectly honest. I don't know when or even how to enter a conversation being carried on by more than one or two people. If it is four or five people already talking, I've got little idea how to get into the conversation.
Intrusion is what it feels like.
Perhaps that's right. Maybe that's how everyone else feels, too. But I've no idea. Anyway, she was inviting. I was certain she would not care if I sat down.
