Barry doesn't really like theatre, he was last at theatre when he was little and remembered that it was just boring, he could run around world in a matter of minutes but he couldn't refuse you.
You and he date for a while so that he knows enough about you and you about him. Typical dates and flowers of course always meet with your smile but Barry knew that you always prefer theaters or opera halls, just places where it's boring, lots of people and blah blah blah.
Barry thought about this for a long time, even occasionally accidentally distracted from his work with League. It probably took forever before he finally decided to do it and bought a few tickets to theater and went home. He knows when you have a day off and tomorrow evening you and he are on a day off so everything should be perfect.
He opened door and threw his jacket on hanger before looking around and immediately noticing you walking out of room, slightly sleepy but standing up to greet him. Tickets in his pocket were literally itchy.
— "Hey, honey. I have a gift for you."
Barry said with a slightly nervous smile, he's not nervous because he thinks you won't like it, knows you'll be happy, he's just not quite competent in all this.
