an icy plunge and a blue flag

For completion of a class/degree we all had to take a swim through some icy water. This did not bother me too much but the thought of having to walk home in the icy wet clothes was worrying for me. I was working on creating blue flags. I had cut out a number of them and was working on the last one- it was going to be a very long one as I was cutting for quite a while. Were the flags for the finishing ceremony?
