Grass pierces concrete

Today at work I was in the office talking to a tearful mom when one of the kids knocked on the door to interrupt and give me a sealed envelope. They were on the way out to recess and she had an urgent sense of getting me this letter. I opened it with the usual feigned interest and gratitude to find a string of six letters written at the top of the page, in pencil. “^valor” is what this 4 year old had written. Hm. Later I thanked her for the letter and asked what letters she had written and she said, “I don’t know, look it up on the computer!” She had just chosen some random letters and actually spelled a word (aside from the first symbol.) Is God trying to tell me something about bravery???
