Have you ever lied to protect yourself?

I lied and said my mum was at the professional fee earning level of her career when she's actually an assistant...
Because people kept trying to dig into and sabotage my life for thinking I was rich or involved in something illegal.

The only nasty thing was because I work part time it got fed back to my manager and they collectively tried to force me into full time because they thought I was living off my mum.

Funny thing is if they really knew, I'm the one that has to help my mum out financially even though she's earning a full time wage at a rate I wouldn't even if I was full time.
