Samantha's Christian Message

Samantha, my 7-yr-old granddaughter says the cutest things. The week of Spring break while spending the night with me she read her Bible before going to bed (always does). While reading she looked over at me and said, "Grandma, the kids at school know I am a Christian." We discussed that and she said, "Sometimes when kids are saying or doing something and I walk up they stop and one says, "Don't say (do) that, she's a Christian." Now I got to thinking about that and I wonder just what do 1st graders have to stop doing or saying when a Christian walks up?
