Hello moms please help me!

So yesterday was my daughter’s first day of school and I drop her I told her teacher I will picking her up later. And I went with my friend to get her because her daughter goes to the same school and I was waiting in the car with the baby until she gets her daughter and come back to me so I can go get my daughter too but instead she brought both of them. And I asked how did she u get her she told me the teacher wasn’t looking and she tried to talk to her but she didn’t listen so she got them both they dont even go to the same class. The teacher doesn’t know my friend at all. This is so weird and making me so worried.
