Will watch 50 minutes of an hour long show and then switch the channel, so you are unable to watch the end of the show.
DH just did that to me. It's so annoying. The worst part is I was not interested in Orange County Choppers to begin with, but damm it if you are going to make we watch 50 minutes of the show I want to see the finished bike..
Okay, vent over.
What differentiates an average host and a great host is anticipating unexpressed needs and wants of their guests. Just because the want/need is not expressed, doesn't mean it wouldn't be appreciated.
