Low key Teen events

I recently ran a teen event in my library, I provided snacks, drinks and ARCs of new books and gave them space to just hand out and enjoy themselves, I had nine attendees that appeared to have a good time in the library. I think we often try to do too much to entertain teens in libraries instead of letting them discover the joy of just being in the space. I am in no way advocating a move to not organizing special events for teens, but instead have them occasionally and build teen engagement by welcoming them in, feeding them and leaving them to their own devices while being on hand to chat and introduce them to all the library has to offer if they show an interest.
