After missing her eldest son, worried for her youngest child, being constantly by an ex-husband who at least appears to have given up making up crazy stories for why he got fired even as she prays for him, and the final straw of a miserable rainy day, this lady decides to blow off some steam by taking a break from her choir practice and hanging out with a new friend whose sense of humour she enjoys, perhaps getting a little carried away cutting loose for the first time in years, and forgetting to let her child know where she is. It's just another quiet day in her quiet town with no knowledge of anything sinister going on, so nothing wrong with having an impromptu party.

This means she's the worst person ever, right?
