"The Holy Ghost has hair when He's cold."

Dear Oliver,

Tonight I was laying next to you, tickling your back as you were going to sleep. I had just finished saying a prayer. After a few seconds, you opened your eyes and asked, "How does Heavenly Father hear our prayers?" I told you Heavenly Father is a little different from us; He can hear everyone talking to him, even if we all talk to Him at the same time. You then asked how Heavenly Father can talk to us. I told you we can feel Him in our hearts. You said, "But I can't feel him." I told you that you will recognize that feeling someday. I said the Holy Ghost helps us know what Heavenly Father is telling us. You said, "I can feel the Holy Ghost in my heart right now." I said, "You can? What does it feel like?" You said, "Soft." I told you, "When I feel the Holy Ghost, I feel a warm, peaceful feeling." You said, "What does the Holy Ghost look like?" I told you, "We don't know, bud. He's invisible to us right now." You said, "The Holy Ghost has hair when He's cold. Did you know that?" You pretty much turned over and fell asleep after that. You didn't see the tears running down my face as I thought of how your little testimony is growing. I felt so grateful for this teaching opportunity. You are such an amazing little boy.
