Men at work.

Early this morning a large lorry turned up in front of our apartment. Two men got out and opened a man hole cover. They then went for there breakfast.`[that's when the pic was taken] They returned one hour later with another van and three more workers if that's the right word. We watched as they got a small ladder out of the van and two of the men went down into the hole. When we looked a little later one of the vans had gone and the cover was back on. I hope that the two men who went into the hole are still not down here.Ha ,Ha.
Why were they down the hole what were they doing? One of life's mysteries.
