"Old people" probably bring their children to watch other children perform songs made famous by ABBA, the greatest group ever to go on stage, who were also adults. When will you children begin growing up and stop making stupid comments?
Młodzi nie lubią takich nasiadówek, wolą potańczyć pod sceną, coś jak na juwenaliach, nie mozna też tam wnosić alkoholu, poza tym bilety pewnie za drogie na studencką kieszeń, a nad morzem pełno pensjonariuszy na wczasach. Why so many old people? The first reason is that young people don't like sitting, they'd prefer dance in front of stage something like Woodstock rock festival. Another is that Sopot is a seaside area where are lot of sanatoriums :)
