My memory of Barry is his relaxed Santa Clause laugh... a kind of "Ho-Ho-Ho" but nothing boisterous. I remember this laugh particularly one night when he explained to me the phrase "moot point", I had (until then) always confused "moot point" with "mute point". He was amused by my ignorance, but in a tender way. He managed to correct me with good humour and without a hint of supercilious scorn.
