A short lunchbreak, but walking amidst beautiful trees and tranquillising blossom, in London's Lincoln's Inn Square, wandering and wallowing in atmosphere rhythmic with luxuriant energy, as a late Spring coincides with early arrival of a Summer day.

...and then returning to work, steps relaxed and reluctant in the sunshine. Without intention I find myself cheerily humming as I walk... but a familiarity to the tune catches my attention. In sync - but oddly, following the birdsong heard just before - other pervasive environments mutate the mix. Unwittingly, it is a computer dial-up tone that I hum!
