So if we don’t have a set age, who decides if your mature or not.
At 16 I had 20 year friends, at twenty I had 16 friends.
At the age of 19 I had a girl of 15 knock on my front door who I had only met once before previously.
Now at 15 she was a fine figure of a young woman.
Anyway she knocked on my door and on opening said she was going to suck me dry.
Now people I knew at the time would have invited her in an closed the door, I stepped out and closed the door behind me. Went for a walk and basically asked her what are you like.
I did this because, maybe some what I knew she was 15 but mainly because based on both meetings I saw her as damaged ( I am not trying to be derogatory with that statement) and thought I would be taking advantage of the situation.
I saw her 5 years later with someone else in a pub looking absolutely beautiful and I did kick my self a little bit.
But at 19 I did not look at her at 15 as a child but as a peer, a peer who was under the age of consent.
It is complex but a line has to be drawn in the sand to make an initial arrest possible and then digression will be the the job of the CPS or the courts .
