Would this make you angry?

You find an activity you would like to do. Nothing immensely exciting, but a cool little thing to do to fill time. Your SO is not interested in doing the activity because it’s just not their thing. Your SO tells you that although it’s not their thing, they will go with you since it’s important to you. Every time you bring up the activity, they give you that same answer.

Would you be angry? Why or why not?
