The Gallabreakfast is the Realist Societys celebration of May 17th.(more on this day on Wikipedia). Here its a nive breakfast buffet, speaches, toasts, music, a parade and someone gets to swim in a fountain.
This obviously takes place on the morning of may 17th, when the spring is showing itself from its best side and we all can remember nice dresses, ice-cream, sodas and the good times of yesteryear. Additionally there are some historical aspects to this day, as many of the party-traditions experienced are more than 150 years old. This is how the students partied in the early 1800s, drinker beer like a runner drinks water during a burning hot New York Marathon. It's never a dull moment on this Gallabreakfast and it should absolutely be experienced!
