I always open the door. Many , many years ago, when my children were all small, hubbie went off one Sunday evening taking my parents back home. Six children under 8 years all in bed and asleep, I tackled washing up and the front door bell rang. 9.00 pm!!!
When I went to the door there were two young boys (15/16 years old), both taller and bigger than me. They asked to come in to ring their parents as they (said), they were being chased by a gang.
I was not sure what to do. The thought went through my mind of trying to explain to the police that I had allowed these two youths into my home........etc.......etc.
This was long, long before mobile or even cordless phones. Anyway,, I asked for one of their parents telephone number, which was in a town about 15 miles away from where I lived, left them on my porch, shut the front door, went in and rang that number. Yes, they were telling the truth..........so I brought them in to talk to that horrified parent. And, whilst waiting for them to drive to me gave them a cup of coffee.
They had told their respective parents they were just going into town (three of them - never found out what happened to third lad), but got on a bus and got off at the terminal which was close to Epping forest. As they did, they told me they were chased by a gang of boys and the two of them ran in one direction and their friend in a different direction. They rand down this road in our smart suburb and each time they saw a light on they tried to ring the bell, but no-one answered - until they got to my house!!!
So pleased I did answer that front door and was able to help. Those boys were terrified of that gang and also as to what their parents would say. As my own children grew up always hoped if they did something as silly, some adult would be willing to help them.
