Can't please everyone 🤦‍♀️

So a few weeks ago my mum bought my LB a new car seat for her car and my partner was annoyed, today I've picked up a second hand pram to keep at my MILs to save me taking mine every time I go there, when my boy was 8 weeks old me and my mum went halves on a pushchair which was £65 as my travel system just wasn't right for me and baby, now I've told my mum that I'd rather keep the second hand pram for my everyday use (it's a Joie) she's mad that I want to leave the pushchair at my mother in laws 🤦‍♀️ she doesn't push the pram anywhere so why is she so offended?
