I probably am being unreasonable, but hear me out. Just having a brat really.
I work in the city of London in a finance role, supporting fund managers. My mum has asked what I do and I have told her many times what my role is and how it supports the wider business. She just doesn't understand it and when I try to explain, she says "it's all so complicated!" And won't even try to listen. She is in her 60's and was a SAHM her whole life. My brother works in digital media sales and it's the same with him. She thinks he works with computers and I'm a secretary. She doesn't seem to understand that I'm not in a typing pool.
It's a stressful, serious job. I have tried to explain, she doesn't seem to understand that women can have important roles in an office environment.
Do your parents understand your job if it's not something like teacher or nurse? Maybe IABU! I give up with trying to explain it now!
