I feel like I shouldn't go to my mom's concert
It's your mom. Why do you not want to go to the concert to suppose her?
I know she's going to be so mad at me, but it doesn't interest me.
You should be there for your mom. This is her big concert and she wants you there. Please go and be respectful.
Fine but I'm still not interested in the concert.
Awesome! Your mom will be so happy, and that's all that matters. The concert itself is not important; it's about supporting her passion and dream.
