Barking at Lucia

We celebrate St. Lucia in Sweden today. On the morning walk, we saw some young people walking in a St. Lucia procession, singing Lucia songs. Daniel got really mad when I barked at them and told me to stop. I did, of course, but I could not stop glaring at them. I was the only one who barked, so I was the only one Daniel got mad at. Was I the only one who heard that they sang out of tune?
