During a period of his life my son shared a flat in Sauchiehall street with a few mates. His grandmother gave him an old leather sitting room suite she was replacing, and he took it over to the flat, dumped it in the close entrance and went off to find a parking place for the van. When he returned, the suite had walked.
He lived in fear she might ask him how it was getting on...
Life in the grey zone.
Not only pickpockets are quick!
