I had a very similar situation. Jess was friendly with a girl named Mayah from daycare & they just happened to be in the same Kindy class. After the first week it became apparent that Mayah was one of the naughty kids & always had her picture on the 'red face' (exactly like your red dot thingo) & that's where the friendship ended. I was a bit sad to begin with, but I knew the teacher a bit on the side & she said she would discourage Jess pursuing that friendship as this kid was REALLY naughty.

I think in the whole scheme of things, it's probably a good trait to have, as it shows the kids are capable of making an informed decision of their choice of friends.

In Jessica's case, I think she was just too scared to be on the red face. bahahah
