What should i do in this situation?
I have a best friend. I've known him for a long time. We like to play various computer games together during our free time from work. During the New Year holidays, a live event took place in the game we are playing. Unfortunately, my friend had to go on a business trip. So I suggested to him that I go through this event from his account, despite the fact that I was ill. He agreed. Unfortunately, I did not complete this event, although I tried, and I told this to my friend. He was very disappointed and spoke out to me. It made me very uncomfortable and sad. How should I behave in this situation? I have not encountered such a situation before and do not know how to behave, although we are grown-up people.
