Sorry ..thread title is not as exciting as what it really is !...but my Mum has really upset (and worried me) on her opinion on this ....
Last week I said goodbye to my son at the door as he went to school at 7.30am..
I am still in pj's and early morning mess and go into kitchen to put kettle on for another dose of caffine ...door knocks....I opened the door (without checking) expecting ds to be there ....I even had my silly face on ready to say "what have you forgotten ".....
No ..it was a meter reading man showing his badge ...but without my glasses on it was a blur..
I said I would get them ...closed the door and then came back and gave him the numbers(quickly grabbing a cardigan)....I gave them (through the security chain)!
My mum said I was very "rude" not to have let the poor man in and to close the door on him was awful 
What would you have done at that time in the morning ...?
