Is the "____ is crafting a response" message a tool designed to teach patience?

First of all, I love the fact that people take their time and come up with thoughtful responses to the questions here. But sometimes I can’t imagine what’s going on. I see this message and it’s someone I respect and can’t wait to get the response, but it will go on forever.

If you are guilty of this, what keeps you in the answer box so long before pulling the trigger? Are you crafting an answer and doing research? Are you typing really slowly? Did you decide you need a nap?

I’m going to use this as an opportunity to practice my patience. I am curious though – how do you commonly approach answering questions?
