What does it mean when you have multiple faces? Whether online or offline?

You can’t be trusted. I don’t know which one to talk to and that bothers me

You act different in different environments

it means you need to stop taking lsd.

The character is so inconsitent and flawed that it attempts to please as many people as possible at the expense of ones own dignity. 'Running with the hares and running with the hounds'; Janus-faced; artificial and deceitful.

Like back stabbers? Or...

Some people express themselves differently according to how much they trust. Family vs. close friends vs. acquaintances vs. strangers.

That and you're generally pretending to be someone/thing you're not.

You may have multiple personality disorder.
