1- Explaining how it can make profit. well making profit is top priority of every company, but at least explaining that a lot is not really feeling good to us tho :)

2- Reporting progress of something you work on.

3- Confidential data. If you're gonna work/found startup, you probably should forget this and be openminded. I saw some who really don't want to talk about (even) brief blurb of idea.
