Was I wrong to walk off when my boyfriend and his family wouldn’t stop speaking a different language on a day out?

My boyfriends 2 siblings came to visit. I went for a day out with them. They would frequently speak to eachother in their own language , joking and laughing, despite all being able to speak English. Eventually I got fed up, and whilst we were in a museum I walked off and looked at stuff on my own. Was I wrong to do this?
