Cathy may be invisible to the main residents of Heidelberg Tower, but not to the receptionists. Laurel and Hannah know who Cathy is. They enjoy their morning banter over tea together. There are many invisible people in Heidelberg Towers. Doreen has tried extremely hard to be one of them, but she just isn’t. Her attempts to shuffle around the edge of rooms are so quirky that you have to really look at her. Doreen is terminably ‘Noticeable’ like Eugene Felnic in the Grease duopothy.
On the other hand, Diana Clutterbuck is eminently forgettable, except for her charming name. Laurel and Hannah agree that they couldn’t put a face, gait or dress style to that name. Neither of them will recognise her when she walks through reception in the morning. There’s nothing left to do but to email the whole building to get her to come to reception and collect her parcel. Now everyone will know her name, but she’ll still be invisible to everyone except Laurel and Hannah.
