Today is Sunday, you usually always cycle on the bike path of the central city park on quiet Sundays, today you tried your best to climb the hard hill of the park with your bike, but your little body was not ready yet, so you wanted to brake. but your bike fell on you and you fell with the bike, you heard the sound of the pedals of another bike approaching, a tall boy was riding his bike, he got off and slowly lifted your bike out of your sight: "if you can't control the uphill, use the soles of your feet instead of using the brakes."
