HOW missed?

       It took me until 09:42 to realise it was actually Monday - SO - I went out to collect the Milk.  Looking along the wallI saw the one empty I'd put out and thought " ODD; I'm sure I paid the Milk Bill.  It was quite a few hours later, when out Blip hunting that I noticed the two under my nose.  They're virtually NEVER left there; twice in the last two-year I THINK.
       A bit odd, considering I spot things like this and this.
