Looks like a hostage situation: wraps his arms round their shoulders to dominate while they look uncomfortable

All except David Agius, who reciprocates with his own arm and looks thrilled. Body language is so important. When a man puts his arm round the shoulders of another man who is not his familiar or close friend, and who therefore does not reciprocate with his own arm round his shoulders, what that man is doing is dominating his target. The men in question should have shaken Delia’s arm off. They look like they want to, so they should have. It’s a complete invasion of space and inappropriate – the equivalent of a woman putting her arm around another woman’s waist for a photograph when that other woman is not her close friend.
