I've been wanting my girlfriend to watch videos from a concert I went to.
Why do you want her to see it?
I think the videos are cool.
Including your partner in viewing your concert videos is nice. It shows you value her opinion on things.
I'm glad you agree, I think she would really get a kick out of seeing them.
I imagine she would be appreciative that you would want to show her those. Maybe make an event out of it by making some popcorn and having a little date night.
