We have regular visitor to our house who is a teenage boy with moderate global learning difficulties. He is a nice boy but he has a habit of putting his hand down into his pants when he is sitting down. He does this all the time. His mum sees this happening but doesn't say a word. I have a ten year old daughter and I don't like this. It's really difficult to say anything to the mum she doesn't want to know and makes out Im the one with the issue. It's a difficult one and I don't know how to approach it. Am I right to feel uncomfortable
