You can look at it as not being invited to an event, a party, taking part in someone’s life… or does it feel like you are not invited to your own life???
Even worse you can look at the prompt as having been invited and then being uninvited. Write about what that feels like (does a 2-by-4 come to mind?).
Or if you had to do this to a person, un-invite them from an event, what did that feel like? Did you think they deserved it? Did you feel bad?
