I also have the atypical plastic family behind me. Mum, Dad, son aged 6 and daughter aged 4. I sit in the Kop. The son asked me to sit down when the players came out which found slightly odd but gave him the benefit of the doubt as I'm over 6ft and it's not too much trouble missing out before kick off. However, he then spent the first half kicking my seat until I told him if he could stop that. At the same time, it was clear Mum isn't very interested in football. The daughter was drawing and kept dropping crayons on our row.
Then towards the end, I sussed this son was an Arsenal fan as he kept saying 'score' and cheering them on any time they did something decent. They left at 88 minutes and they were at Everton game. Despite sitting in the Kop, I now feel duty bound to reel in my language. Why they sit in the Kop when there's a family stand where it was free for under 8s (is it still?).
I really hope this isn't going to continue across the season.
