Sims date ends due to 'too many mean or mischievous interactions'

I just had this happen.  On Thursday, I received a call from a secret admirer.  The sim that got the call is unflirty, and I have so many families in this save that I don't plan on her marrying, but I figured I would see where it goes. On her day off, on Saturday, I had her schedule a get-to-know-you date to get coffee and talk. Two small talks in, those were the only interactions, and he leaves "after receiving too many mean or mischievous interactions."

The other sim did show up on the date with the embarrassed emotion.  I invited him back over (not on a date initially), used the "calm emotions" interaction she received from the Parenthood pack when she aged up to a young adult, and then started the date again; it went fine.  The cause may be the dates showing up in a bad mood.
