And I can easily show I can work a till - I've been an assistant manager in my last job, before the shop shut down at short notice because the owner couldn't have organised a piss up in a brewery...
Anyhow. DD was a bit 'naughty' for the FC yesterday. She had arranged to go to the cinema, to see a 15 film, but she didn't have I.D, and neither did her friend. So instead of calling the FC to ask to be picked up, she buggered off with her friend, only calling the FC when it was time to be picked up. So nobody had any clue where DD was. Apparently they had gone round DD's older boyfriend's house.
And DD pointed out to me that I was a bit hypocritical to be saying that her boyfriend is too old for her by asking me how much older than me her Dad was, and how old I was when I started seeing him. 
I had to grudgingly admit her point - the age gap is almost exactly the same, and I was almost exactly DD's age when we started seeing each other...
I'm unsure how to deal with that one. All I felt I could tell Dd was that when I was her age, I reacted and felt exactly as she does about being told I couldn't see him, but now I'm old and decrepit, I can understand everyone else's point, that he WAS too old for me at the time, and looking back, I can see that there was a huge difference between a child in the last year of school, and a 17, going on 18yo almost adult, who has been working and at College for over a year, and is learning to drive.
I explained to her that the people who didn't want me to see her Dad were only doing that because they cared for me, even though I couldn't see it at the time, as I'm sure she doesn't. I even joked that I will remind her of this when she has teenagers...
I hope I dealt with that the right way, God knows, it's such a minefield, and tbh, she DOES have a point!
