I won't joke

I wasn't annoyed. I knew I was not serious sometimes, but I was just being too relax that I didn't even think of what I said. I felt that playing volleyball was an enjoyable thing, that's why I joked around and try to make the atmosphere more relaxing. I didn't know that this will make others felt uneasy. I will not joke next time. I joke doesn't mean I am not serious, my standard is just there. I can't be as good as you all, but I will try to fight for the ball next time.
