My brother and I

Looking up at him as he slowly walks in front of me, walking a little too fast for me to keep up. Making me run behind him, with my backpack halfway up, halfway down, making it almost look like a beavertail.
"Come on!" He says turning his head, and when he realises I am just half of his height he bows his head a little bit down, to reach just the top of my golden white hairy head.
