I agree, you are saying everything correctly. I modeled this situation with the conference and the object of concentration was a girl in the front row.
But this is not a real life story. From the first word to the publication of the post, 50 minutes passed and everything was finished along with the report and the marriage, and all this is just my imagination ;-))

In addition to just telling the story, I tried to give an algorithm for solving this problem :)
