Tickets to Adult Concert at the Washington Ballet April 16-19?

Hi! I know this might be a long shot but does anyone happen to be selling or know someone that is selling a ticket to one of the Adult Concert shows at the Washington Ballet the weekend of April 16-19? I'm newish to the area and didn't realize they would sell out so quick! I have a friend that I would love to support and curious if anyone has tickets to any of the shows/times?

Thank you!
