NC as this might be outing.
A school mum asked me to do a favour, I didn't mind at all as I've known this person for years, more acquaintances than friends.
We used to live near each other and did favours such as sharing some drop offs/pick ups + our children were friends in primary.
I moved away a few years ago as I got divorced and had to move to a cheaper area, but still catchment for the same schools.
While we were discussing the favour, school mum asked me if I was happy with our child's school. I said yes DC is very happy there and doing well, we've had no issue.
She then told me they are thinking of moving their child out of said school, due to the "lower classes" from X & Y area "bringing the results down".
One of the areas she named is the area myself and my children live in... she knows full well where I live and has been to my house before.
AIBU to think this was very rude and I will be doing this person no more favours?
