'Friday' is about hanging out with friends, having fun. I felt like it was my personality in that song.

I've been saying for a couple of years now that people need to let God out of the Sunday morning box, that He doesn't want to just be with you for an hour or two on Sunday morning and then put back in His box to sit there until you have an emergency, but He wants to invade your Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday.
