I mean in fairness I didn't research what this appointment actually was, I just bought the documents the registrar said to bring. I thought it would be quite exciting going in together and signing the documents together. No no. Get to the door. One sent back to car, separate interviews.They said they were going to ask me some questions. I fell apart 
They compared our answers. My fiancé had gotten my job wrong. I said my job and they said it wasn't what he answered, is there something less specific he might of put? It felt like a riddle. I kept saying last minute wedding meaning just planned last minute, we've been engaged for years. Then I realised they might think that and kept over explaining that it's not that last minute we've been together years it's nothing concerning did I make it sound concerning?! It's not rushed or anything.
She asked if I wanted to put my parents details, I said no. She said your partner did, so I agreed. I couldn't remember my dads middle name. Total mind blank. Then his job. I just kept repeating civil servant and nervously laughing. I asked her if I was doing ok and said I hope I'm not being suspicious. I am who I say I am I just don't test well. She said it wasn't a test. Anyway. She seemed to think I was insane, she gave me a pen to sign the documents and I didn't realise I'd held on to it and at the end she put her hand out and I took it and shook it, she just wanted the pen.
Overall, not the romantic if not slightly boring appointment I thought it would be. Be prepared for a less cute and slightly more stressful game of Mr and Mrs. And brush up on your parental knowledge.
