So the curlette's school had a "school in action" night yesterday - to show next year's new intake various things they can do when they get there. The curlette (a freshman, or for non-US types, in her first year at the school) is in the acapella group, who performed at various points.
One of the guys in the acapella group is a senior (i.e. in his last year at the school) and wanted to ask a particular girl to the "Prom" with him. So he decided to make the "Prom proposal" a special thing - he got the whole acapella group to serenade her as he handed a bunch of roses in front of what was by now a huge audience.
She said "I'll think about it..."
