Ds is best friends with a little boy C. C's mum likes to encourage his friendship with R (her friend's son but in the same class). Ds is rarely invited to go play at C's house despite C begging his mum on the playground (embarrassing I know) so we have C to ours quite often (at least weekly). Anyway it's C's birthday this weekend and ds has bought him a PS2 game as he is getting a PS2 for his bday. So yesterday after school we delivered it to his house and outside were C and R playing. C immediately left R and came running over to ds. C's mum came out and over to the car and said "does ds want to stay for an hour?" and proceeded to explain that she had inherited R after school and it was unexpected. Anyway ds couldnt stay and we arranged hurriedly for one evening after school next week. When we got back ds said that C had told him in the day that R was going round after school. Why would she lie and more to the point, what's wrong with my ds that she doesnt want him there? Ds is leaving the school next week and I would like him to stay in touch with C but am wondering whether it's really worth trying
