This is actually rather simple. All you have to do is describe 5 objects from the room you're in without actually saying what the object is. If other members know what you're describing, you are great at describing objects! If they don't know the object based on your descriptions alone, ask them how they would describe it and try again with a different set of items! (To make things easier, use things that are generally well known, ie, books, desks, etc. Nothing like a statue, because people might not get it if they never seen it.) Good luck!
