Happy Birthday

I’m standing at the entrance to the exhibition, dressed in an evening dress. I’m handing each visitor a red rose and congratulating them.
After all audience are at the exhibition I’m asking them to put their roses in a huge bucket. I’m singing the song: Happy Birthday and I’m asking the visitors to sing with me. Today is the anniversary of the school we all visited, we all have birthday today. Each visitor has to take their roses at home at the end.
