i'm in SW12 and i arrived home as someone was walking up to the neighbours door - over the fence he asked "I'm selling a home security system you can control from your phone, do you have any home security installed?" I said "there is no way i am answering that question! don't bother ringin our bell as my husband will just tell you to go away"
my husband was not home - but I was standing there with my 2yr old...
he muttered something about me being a dogs mother....
luckily my elderly neighbours were not home.
