Please remember that behind the door you are about to knock on there could be a vulnerable person who is scared to answer the door, maybe a pensioner, a Domestic violence survivor scared it could be their ex, a person with P.T.S.D, someone with dementia or someone who is scared of the outside world. If someone has Halloween decorations up and a pumpkin on the doorstep then go ahead, but leave the unlit, quiet houses alone.
