I found another movie with some slight resemblance to this one, it was a 1979 tv movie with Shaun Cassidy as a mentally challenged boy named Roger and his girlfriend who is also mentally challenged. The film is called "Like Normal People".
shareYep, and the writer was Joanna Lee, who wrote many fine Flintstone, Gidget, Brady, and Gilligan shows BUT, we gotta face it, hasd two, TWO, couch tater
annals of shame on her TV/movie resume--The Great Gazoo on the Flinstones and Plan...NINE..FROM..OUTER...SPACE!!:)
BY then, in the 1970s, she was experimenting with writing many different dramatic type sof shows, ranging from the gentler Waltons to these women in distress flicks, that are still done today by modern day writers for big budget theatricals and for television....only now they make the women kick asses!Passed away in 2003..9 yrs RIP Plan 9 woman.
