not just accessories

Do you feel comfortable,
When in a group of three friends, you talk about something to one of them, while the other one knows nothing about it?
Do you feel comfortable, when that other someone looks mystified, and you don’t even bother to explain or, better yet, to stop that ‘inside’ discussion?

When you want to talk secret, do that privately.
When you don’t want others to know, don’t talk about it.
Heyy, that other person is a PERSON, not just accessories, you know…
Has ears, has eyes, has heart...

courtesy..courtesy…
does anyone know what that means nowadays?
