I had a concert today at 12:00 and we were first up and we had to wear special shoes called in serbian languange (opanci) which had shoe laces that had to be done the right way and i did it and before we were up i checked them again but when we started going one of the laces untied itself and i couldnt do very well sunce i had to Make sure i or someone else wasnt stepping on them and it was my worst played concert i play as far as i can remeber (btw the laces were Long)
