Gladys is a shameless gossip, as revealed when she tells Mr. Brown’s entire class about his birthday and Miss Courtney about Mr. Brown’s “engagement” to Danielle. She used to sing in a choir and was known for being able to dance The Veleta skillfully. She also has a sister who fell in love with her 30-year-old milkman when she was 65.
Gladys tells Mr. Brown a little about her husband Wally in “Season 2 Episode 7”, but she later says Mr. English reminds her of her late husband. This makes it unclear if Wally has died or if she’s referring to a man she was married to previously.
In Season 4, Gladys is replaced by Rita.
