If you have a half-filled cup of coffee, or tea for that matter, It means that you are working strong and have too much noisy chatter
inside your head while you work, to succeed at your grind, or chess game where you work out moves from your fast fantastic mind.
A half-full cup of coffee means you needed a’lil break at that time, or a soothing cup of tea would help slow the over active chime.
But when it filled and some was drank, you went right back to your game deployed. And left her standing strong and full, to help again if you get annoyed.
So you’ve reached the level Half a Cup, if one’s heart needs help drink the other half Cup.
