The title says it all, so here are two examples.
Zevlor and Aradin argue, I cast Friends to prevent Aradin from punching Zevlor. After dialogue ends, Zevlor gets angry because he was Friends’s target.
Lae’zel tries to convince Kithrak to take us to the crèche. I cast friends to signal to Lae’zel to play along. It works, Kithrak leaves and Lae’zel get angry because of friends.
It makes more sense in the second example, because I was trying to convince Lae’zel of something when casting the cantrip. However, the situation felt more like deceiving Kithrak than Lae’zel and why do I need to convince her to do something she approves of anyway?
There’s also the possibilty that Friends works on everyone in the dialogue, but I haven’t noticed because, on both occasions, one of the participants left before Friends ended.
