When delivering leaflets, catalogues etc l suggest you take something to poke them through with!
My friend was doing this last week in Hoddy' when a dog savaged her hand and she spent 4 days in Broomfield hospital having her hand stitched back together!
l asked her why she had put her hand through the letterbox and she said she didn't want leave them poking out of the flap and the brushes made it difficult to push the leaflets through.
l sometimes do this with my granddaughter for scout jumbles, school fetes etc and go cold at the thought of something similar happening her
