I am being formal (I think)

I don’t know what to say right now. But all I know is that I cannot say informal things. So basically I need to be formal right now. But I have things to talk about. I am just saying that but I actually do not have anything to talk about. So I will talk about things that come to my mind. For example, I need to go to my piano academy in approximately 10 minutes, And now 10 minutes turned into 6 minutes. And the fact that I have to finish this because today is the day I (we?) go to PEAI. So I need to finish this very quickly. And I am listening to music right now but I do not know the lyrics or the title of the song. But right now, I think I am talking about the things I am doing right now. Not the things that I am thinking about. Or things that come to my mind. I actually do not know how to be formal that much. I just usually do not say anything when I need to be formal in front of a person that I did not know. But I should go to my piano academy now.
