Plot.
"Sorry!" is based around Timothy Lumsden who, 41 years old in the first three series (his age increased to 42 and then 48 in subsequent series - Corbett was actually 50-57 during the series' run), is a librarian who still lives at home with his domineering mother Phyllis and henpecked father Sidney. Although quite shy around women, Timothy longs to find love and leave home, but Phyllis is always against the idea, and constantly manipulates her son into staying at home. One of the catchphrases of the series is Sidney's "Language, Timothy!", typically said in response to something that's been misunderstood as inappropriate or offensive. Timothy usually responds "Sorry, Father", but sometimes snaps "Shut up, Father!", to which Sidney replies "fair enough".
Timothy's friend Frank and sister Muriel urge Timothy to stand up to his mother once and for all. Muriel had successfully left home and married Kevin, and as a result is viewed with distrust by her mother. 
Cast.
Barbara Lott, who played Timothy’s mother, was only ten years older than Corbett.
