The New Adventures of Old Christine (2006)

Season 1: Episode 12

Shut out once again by the cliquey, judgmental moms at Ritchie's school, Christine runs into a down-to-earth working woman, Belinda, who invites her over for a drink after work. Belinda's job, however, isn't quite the type of position Christine expected her to hold, which throws yet another wrinkle in her attempt to fit in with the other school parents.
