DD does an after school activity. I usually pick her up and walk her to it unless the weather is horrible in which case we get a taxi. Another girl in the year above also does the same activity and yesterday her mum asked if I'd be able to pick her up and take her with dd. I said that was fine but unless weather bad we'd be walking. Her mum said "Assumed you'd taje a taxi or drive, don't think she'd manage the walk I'll make other arrangements" and walked off.
The girl in question is in the school gym and net ball team so I've no reason to believe she has any physical problems.
AIBU to think mother was being rude and her dd could easily manage such a walk?
