RE: Omitting The Truth: The Subtle Art of Lying

It does really depend on the context, but generally needs to be avoided for the most part.

I did something similar last week. I told my mum to give me her laptop to do office work related stuff for her. She did but I didn't do just what I told her I'll do, instead I also tried out a couple of software upgrades and applications on her device. Had I told her that's what I was specifically going to do, well she'll never give me her laptop.
