Although the lake was frozen, it was sunny today. My mum and I decided to go climbing. We put on thick down jackets and set off. It took us one hour to get to the summit of the mountain using the path. Suddenly, we heard a call for help. My mum and I hurried to the call and found an old man having a heart attack. We were scared and didn't know what to do. Just then, we heard an ambulance arrive at the foot of the mountain and four people in hospital coats rushed over to us. My mum and I shouted to them,"The patient is here!"
