Recently. A close friend had hired 'Elsa' to do some dancing and general entertainment for the party kids. They were super excited waiting for Elsa to arrive.
Doorbell / intercom rang, 'hi, I'm here to be Elsa?'
Comes up, knocks on the door. Comes in. Short dark hair, beer bottle bottom glasses, jeans, hiking backpack (and don't get me wrong, none of these things are terrible..... she just wasn't quite in character!!!)
Loudly, 'hi, I'm here to be Elsa, where can I get ready?'
Obvs totally ruined the mood for the kids who, age 4-5, genuinely thought that Elsa was actually coming!
'Elsa's wig kept coming loose. None of the kids were that bothered since they knew she definitely wasn't Elsa. So she started doing magic. But by magic I mean card tricks well over the heads of the kids, and, I shit you not, a trick with a magic rope that involved her putting the rope round a child's neck.
She didn't do her full hour, was asked to leave, the kids were very content running round with the balloons to be honest and nobody choked to death on a rope so that was good.
My friend was MORTIFIED but I reassured her that we all had a good time and her daughter prob wouldn't remember it. For the parents it was an EXCELLENT party - champagne, nice bbq and all sorts of lovely food!
