it's fun lying, I been lying my whole life, gets you out of trouble a lot

I get bored😔 but I never lie about my age

That is because people just use the age as a search parameter and look for people only within the age bracket.

It makes them feel young and sexy

I'll guess it gives them a cover for that...

I think that they are miserable and hate their lives. So much that they live in a fantasy world as someone else.
