An 18-year-old Oak Crest woman was arrested after allegedly hitting her mother during an argument over whether the mother should give the daughter a pedicure.

Police responded to 2 Oak Crest at 9:45 p.m. Wednesday, June 24, on a report of a mother and daughter arguing, Detective Mark Cappelli said. The woman, Morgan Spar, 18, of 2 Oak Crest, was charged with disorderly conduct.

The mother told police she came home from work and her daughter became insistent her mother file Spar’s broken toenail, Cappelli said.

After the mother filed the nail, Spar asked her to clip it, Cappelli said. Spar then allegedly yelled at her mother and locked her out of the house when the mother stepped outside in response to an argument over whether she would paint Spar’s toenails, the mother told police, Cappelli said.

The mother then agreed to paint Spar’s toenails, but Spar allegedly hit her mother on the head when the older woman began to lecture her about her behavior, Cappelli said.

The mother tried to walk away, and Spar allegedly hit her on the back and blocked her mother from entering her own bedroom, Cappelli said.

Cappelli said Spar acknowledged her behavior, but added her mother cursed at her when Spar unlocked the door to let her mother inside and pushed Spar backward when Spar got up during the episode.

Spar was released on a promise to appear in state Superior Court in Stamford on Thursday, June 25, according to Cappelli.
