FRESHEN UP, HIT THE BOOKS, SQUARE MEAL, HIT THE SACK & SLEEP LIKE A LOG

 Returning home from the playground, he freshened up (washed and became clean) and sat down to hit the books (started studying seriously). Later, he had a square meal (a full and proper meal) and finally hit the sack (went to bed) where he slept like a log (slept very deeply).
