The sunshine of this weekend saw tens of thousands of tourists descend on the seaside towns of the North Wales coast but what struck me most, wasn't the crowds, but the examples of solitude and loneliness I saw along the piers and promenades. Most of the people I saw on their own were sadly older people, with the odd exception of a young single mother here and there. These solitary figures either stared blankly out to sea or silently watched the noisy, bustling families pass by, just invisible observers.
