Becaause I do. DS1 has been playing with a lad since we moved her 2 years ago. Since then other lads have got friendly with friend1. To the detriment of DS1, who is feeling more and more left out. He ahsn't been out any afternoon last week or at all yesterday. His friend 1 though and theo other lads plus friend1's "girlfriend" (IMO ridiculous at 10 years old) seem to spend all day round friend1s house and never coming near DS1. It turns out frined 1 has also invited all these other lads to sleep over at his house on his birthday, but not DS1 and DS1 is very hurt by all of this.
I know I can't intervene, but I feel so sorry for him especially as he is suppsoed to be going to high school with this lot in September. Which brings me to another problem but that's another thread!
