Au pair had told us some time ago that she wanted to stay with us for Christmas and go home just after - all fine.
I had asked her a couple of times in the last month if she had booked her flights, and she hadn't got round to it yet. A couple of days ago I noticed she posted on facebook that she had booked her flight - didn't mention anything to us. I asked her today, and yes - she has booked a 6am flight from the 5th closest airport to us 
I asked if she had a plan to get there, having previously explained this airport was hard to get to and there was a coach running once a day to it. She was hoping we would take her, or she would get a bus or train. To be fair we had vaguely said that we would be visiting family about an hours drive from this airport after Christmas and we could possibly combine it with a visit to London/getting her to a train station nearer to the airport. However, she has booked the flight without checking the time or date with us at all!
Am I being unfair to be really annoyed by this expectation that we will arrange our plans to suit her, when she didn't even tell us about the flight until I asked?
