The Way Less Travelled

Had to go to the Post Office Depot today to collect a parcel - it was a bitterly cold walk, but on the way, saw this passageway, obviously not much used - would like to follow it some day...

But had to get to the Building Society to pay into my daughter's account - and when I got there, found I'd lost her passbook. Retraced all my steps - and they were MANY, but did not find it, so went back and spent eons cancelling it.

Just came upstairs to post my blip and there was the passbook on my bed. Ho hum.
