Dreaming in Digital

I was in a car with Cookie and his mom. We were headed to his cousin's university because he forgot a banner for a dance performance he was participating in. It had already started when we arrived. Cookie's mom gave one side of the banner to Cookie to hold and ran across the stage to the other side. I didn't see it, but I heard Cookie start cracking up. The song ended soon (which was "Rolling Girl" by Wowaka, sung by Akiakane). He told me at the end that his mom stopped in the middle of the stage in front of the dancers during the performance with the banner in hand. I didn't understand why that was so funny, but it made me so happy to see him laugh like that.
