She is in year 7, he is in year 8 at same school. She does love making dens and exploring woods, climbing trees, etc, and says he does too. I have not met him. When i asked if this was a date she got annoyed with me, said why can't she just have a male friend. Shall i just say no? Invite him to our house instead so we can meet him? I remember when my nephew was his age - he was almost 6 foot tall! Could this be innocent? Did not expect any of this till next year. Help!
