Just

I, and many of the people I know who actually pray, tend to inject the word 'just' into the beginning of the prayer:

"Father, we just..."

Why do we do that? Is it to delineate the request? Every time I hear it, and it comes out of my mouth often enough, I think it sounds discordant.

"Hey Dad, I love you, you are so great, you have prepared such a great banquet for us, but can we just have a coke?"
