It's hurtful to assume things without evidence.
Mindy enters a room to see a broken mirror that was fine 5 minutes ago, only her kids and husband are in the house.
Mindy wants to know who broke the mirror.
Mindy calmly asks her kids about it and none of them claim to have broke it or have seen the others break it.
Mindy immediately assumes that the kid she's on poor terms with is the culprit.
A few minute into the discussion Mindy's husband walks in and states that he broke the mirror.
"Only after grounding the ""offending"" kid for a month does she learn her husband broke the mirror."
