we live in appts so were oK lol,
I used to answer the door at my mums and I loved it but these days you never can be 2 carfull, all it takes is a knock, you open then door and some 14 year old storm your hall and grab what they can (sweets, keys, cash etc) however if you dont answer the door they do stuff anyway
by us mum said last year a lady who lived on her own put a sign up saying please dont knock im not well and cant get to the door, the knocked anyway and then when she didnt answer did all sorts, booted her door, egged and then floured the windows, spray canned her car and silly string squirted so far up the zorst she needed a new one!
People these days ruin everything
