The case of the pornographic magazine

At the end of a half-term my sister and I were with our parents at Waterloo railway station in London. We were waiting for the train to arrive at which point we would say goodbye to our parents and see them again in around five weeks time. I would have been around 9 years old at the time.
As one can imagine this is quite a difficult time for children about to leave their parents and go back to a school they may dread.
In this instance my mother was discussing with my father how she wanted to look for a copy of a pornographic magazine in a shop in the station. Despite my sister and I still being present she was getting quite restless wanting to get a copy of this magazine as soon as possible.
So off she went to the newspaper shop within the station, looking at the top shelves, and purchased a copy of this magazine for herself.
My sister and I found this rather strange at the time.
What I would say now.
For goodness sake - wait for the kids to go before getting your magazine. Also your kids are about to go away for five weeks. Have some discipline and give your children the loving goodbye they need and curb your sexual appetite for a bit.
