Why people hide their real personality?

I do it at work so people will leave me alone. I just want to get my check & go.

Fear of rejection most likely

In real life I think different people have different reasons. Some are hiding behind a lie because they don't feel interesting enough as themselves. Others have shame about something. People have reasons for wearing the masks they wear. Mostly, I believe, the reasons aren't I'll intended. But there are those who lie to get us to trust, so they can steal, or cheat us in some other way.

On line, I think, for some it's just living a fantasy that no one who actually knows them will ever believe.

Because as a society you have all rejected your true nature, so of course ppl hide it, out of fear of rejection. Suppose I was lucky I was rejected at a young age, not that one exactly forgets the feeling and the scapegoating, yeh yol can go do one, if you'd excuse my language.

I hide alot of mine because I'm generally an offensive person, I mean the things I make jokes out of have most people shaking their poor, tiny little heads in horror and outrage. Like when I'm out with my wife and we suddenly hear a screaming child, and I say Jimmy saville must be in town.

Personal life is like condom where everyone wants to hide, but they are interested in sex

It's part of being anonymous. They can safely hide behind the anonymity

Fear of not being accepted? Stems from youth sadly.

Because they fear others may dislike them for it.

A psychosis of some kind.

Because realities are scary. I can't face them myself, how can I put them out to others, just to be judged, rejected and hated?

Maybe they don't like the life they're living and by pretending to be different they can imagine their lives are better.

Because I'm rubbish

Politeness.

Dunno. I don't.

Often, fear of being misunderstood.

Perhaps they don’t like it, or have had bad reactions in the past. 🤔
