Hands up I have NC for this as I am a regular on here but to be honest the details of this will out me anyway but....
We live in a rural community with not many children. DS (5) has a friend very close of the same age and we take turns driving to and from school which is a 20 min drive. On the way back yesterday there was much bickering in the car. When getting out the car my son laughed at the other boy (not nice I know) the other boy pushed my son my son pushed back (you get the picture) and my son ended up pushed into the garage which resulted in 2 teeth missing (they were already wobbly) and his ear needing stitches. I do not believe the
other child intended to hurt him like that and he immediately said I?m sorry. He is a nice kid but they both have their moments.
I viewed it as a bit of pushing and shoving but what shocked me was the other mothers reaction ? she stepped over my crying bleeding child and flounced off home. Wtf. After getting out of a and e I switched my phone on had a text off her saying my DS ran head first into the door to get her son into trouble???
We have not spoken since so assume we are not car sharing today ? but should I reply and if so what should I say. If not how would you handle the awkward school gate situation.
I have had a bit of a chat with the school today just making sure that thinks are OK with them and to make sure they are no underlying issues without giving too much away ? and apparently they are fine at school.
Some space is obviously needed between the two kids?s and as there are so few children locally perhaps they are sick of each other. But; WWYD, would you text back? I did not view it as a huge deal between the 2 of them but am shocked by her lack of compassion. 
I feel like saying ?yes his is ok thanks 4 stitches? but that is not constructive is it? Actually I feel like saying worse but won?t.
I need to set off soon,
would apprechite any advice
