Like most of us my definition of hell has changed, but it used to be unannounced visitors: “I was just passing and thought I’d drop in to say hello!”

Please feel free to head along or drop in to say hello where you can meet staff as well as other teenagers. The society will welcome any feedback that might help it make this a valuable and enjoyable experience for all.

One standout feature is how you can create a room to live on your Facebook profile, enabling friends or family members to spontaneously (tự ý, tự nhiên) drop in to say hello. You can do the same as well by visiting the top of your Facebook NewsFeed and check which of your friends currently have rooms open for people to visit.
