My brain was finally kicking in again.

Kids this age are like puppies; they need to get their blood moving before their brains kick into gear.

Despite her efforts to write an outline for the next week's lecture, her brain wouldn't kick into gear.

This song is about one of those times when your brain kicks in and tells your heart 'good things are worth waiting for.'

No way am I gonna fight you when your brain just got up and kicked into warp drive.

Now there was a short silence on my end as my sad little brain kicked in.

We were halfway down the block when my brain kicked in.

I don't think about it-I get busy talking and my brain just kicks in with the right voice.

At the last minute, her brain kicked into gear.

I opened the car door to give chase, but my brain finally kicked in and made me pull up.
