The plot for "Girl Grief" is a bit similar to Harold Lloyd's wonderful film "Girl Shy", as both play men who are absolutely paralyzed with fear around women!
"Good Grief" begins with a teacher calling in sick, so the school is going to use her son, Charley (Charley Chase). This actually is a good fit, as Chase had a lovely singing voice and used it in several of his short comedies. But Charley is incredibly scared around women...which makes him teaching the class a bit of a problem! And, when the young ladies at the school find out, they make the most of this!
For the most part, this is a funny and enjoyable short. I particularly liked to see Charley throwing a little tantrum (it was pretty cute) and SOME of the parts involving cats. I have no idea why, but the foley artist did NOT use real cat sounds and it's obvious and annoying. Also the bit where Charley dreams he's a cat is pretty dopey. But for me, the BIG problem with the film, despite its laughs, is that after a while they seemed to forget Charley was afraid of women...and this shows poor continuity and writing.
