A lot!!! I have done my share of sleeping at conventions with the elbow in the side, same ol same ol. You would know which scripture was coming before they ever said it. My last convention, my ex asked me sarcastically in front of a whole group of people "what did you learn at the convention this year"? I said not to go Philadelphia and sit in 100 degree heat outside, and if you do, you are going to sleep.
Needless to say, she didn't find it funny.
