I don't use names at all. Not because I want to hide that information, it's just that when I talk, I'll say "my brother said X" or "I saw a friend who did Y". She has never asked what the name of my brother, parents, friends are. Not once. I think she just doesn't care much about their names. Who cares if I'm talking about a specific friend. To her, it's just " a friend". She doesn't care to know more. Same with places. I'll say" I was on vacation" but I won't say where because I don't think she gives a ****.
