@GalacticGal I think you can play that interaction out in your head any way that fits your storyline.
I've had one of my Sim's brothers issue the same invitation to check out the Sakura Tea to her; there's certainly no romantic intent there. My Sim used the effect of the tea to paint a decent Flirty painting that earned her some welcome Simoleons. None of the eligible partners at the Festival caught her eye.
But, at the same time...when I've played a single male Sim, Mrs. Pancakes is one of the Simgals who seems to turn up whenever he's out and about. She's often getting her flirt on, too.
Sims do seem to have a strange ability to know the numbers of every Sim they meet, don't they? :smile:
It will be interesting to see if Eliza keeps chasing Erik, or if the lack of a response to her call gave her a hint. After all, he's far from the only Sim in the sea.
