MrsM is eager to learn as much as possible about Geology now that she is working in the Department so she points to the long rod that the student is holding and asks what it is. MrsM imagines that it is something to clean rock surfaces.
The student explains it is a juggling stick. Because he runs courses on circus skills. His speciality is juggling with fire. Would MrsM be interested in a session or two?
MrsM regretfully declines the kind offer...life is busy enough without setting fire to one's hair...but it is nice to be asked.
