DD has been 'friends' with this girl since the start of primary school. I have know my 'friend' (her Mum) for the same number of years. We have met each other socially many times in the past.
They both started high school 5 miles away from home at the same time and are coming to the end of their first year. I have taken them both in the car all year and was happy to do so because I thought DD and friend's daughter were good friends. I also thought I was good friends with her Mum.
However…I have not seen (or really heard from) this girl's Mum all year. It's almost like I am now doing this 'job' for her and she doesn't really need to make an effort anymore. I get very short text messages to arrange pick up times etc. but that's it. The girl has also turned out to be not such a good friend to DD after all. She is very competitive, ignores DD when she tries to make conversation (replies with one word answers) and is rude to me (no hello, goodbye or thank you).
Today, this girl spent the journey looking out of the window and DD didn't bother with her as she's given up trying.
WIBU to just text Mum and say we're not able to give her a lift anymore even though I know she would struggle to get her DD there herself?
Give a reason? Not give a reason? WWYD?
