I just cancelled Ellie's surgery. She has a slight fever, is very congested, and has a cough. It's nothing that would bother her on any other day. I've been through the recovery before and it's difficult. I'd rather her be in optimal health rather than sub-optimal.
They might not have even done it. I'd rather decide to cancel it then spend a few hours at the hospital tomorrow only to find out that no one will operate on her.
