I discovered it was the temperature.

I have brought a barrel of sorghum to this audience. The name of
the sorghum is "The University of Hard Knocks." I can only pull the
plug. I cannot make it run. That will depend upon the temperature
of this audience. You can have all you want of it, but to get it to
running freely, you will have to warm up.




Did You Bring a Bucket?


No matter how the sorghum runs, you have to have a bucket to get
it. How much any one gets out of a lecture depends also upon the
size of the bucket he brings to get it in. A big bucket can get
filled at a very small stream. A little bucket gets little at the
greatest stream. With no bucket you can get nothing at Niagara.

That often explains why one person says a lecture is great, while
the next person says he got nothing out of it.
