Church.

Alternate Definition.
What you have to get dressed up for so you can be bored for an hour at a morning service.
Want to stop being bored in church? First listen to the sermon until you hear one thing God wants you to do this week or one thing you didn't know before.
Second pay attention to the words of the songs and prayers until you hear one thing you want to say to God. Third, try to say or do one thing to encourage some other person.
