I hate when someone has something important to say but can't say it unless they give you their friggin life story first.
Example...my brother is not feeling well and is trying to tell me he ate some bad salami. It took him nearly 40 minutes to actually get to the point that he ate some bad salami. I first had to hear about all the different brands of lunch meat on the market, and a mouthfull of other non-relevant rubbish before he actually could get to the point.
When I tell him "Steve...my head is swimming" he cuts to the chase...but not before you've agonized over his story.
