Why does it matter so much to you what your mum thinks of your choices?
I don't mean that in a sarky/shitty way, but if she thinks her opinion is the be all and end all and everyone is hanging on her every word before they do anything I'm surprised you've not told her how arrogant she is and to keep it to herself.
Just to butt in, i know i for one revert to childhood status in my mum's company awful i know Agent, but i,ve talked to mates who say they revert to their infant/teen self in company of difficult parent/sibling.
My mum for one acts as if im the Anti-Christ if tackled about her negative behaviour. Its hard, can't live with em, can't kill em .
