Step-by-step explanation:
The winter sports that I enjoy the most are figure skating and skiing.
I have not reached any achievement in sports but I do remember once I went to cheer on my friend.
He had a figure skating championship in his town. I accompanied him in all his training sessions and when it was finally his turn to compete, he got the highest score!
That was a great achievement and it was a great honor for me to be with him and accompany him at that time.
