Sometimes when using just a name in conversation...say for instance...

"Lindsay went to the store"...

Would not identify the person especially to unfamiliars...it would be just a name without identifying context.

But if I said..."My daughter went to the store",,anyone listening would know the context of the person....

Names get used more frequently in conversation if all participants are familiars...It is almost an unconscious act in communicating...

IMHO.
