ITS GOOD TO KNOW

It was Monday and a holiday for most people. My boss asked me to work but i chose not to. Were celebrating my grandfather's (brother of my grandmother) birthday that day too. i asked for a half day of excuse of work but i ended up not going anyway.
It took us an hour drive up on the mountains and since i was working under a photographer, they all assumed i am a photographer too so therefore i am in charge of taking the photos to be emailed back to the benefactor.
While having lunch, a visitor asked my mom,
visitor: "How are your kids?"
It was my grandmother (the wife of my grandfather) who provided the answer. ( as if she knows anything about our lives)
grandma: "Her kids are doing well."
visitor: "Who is she? (pointing at me) is she your daughter?"
my mom smiled but my grandmother still provided the answer.
grandma: "Yes! That's Piwi. aww.. shes very unique! Whats your course again piw?"
i stopped what i was doing and obliged an answer.
me: "interior design, La"
grandma: "Oh, yes. See she's a designer. She's very unique"

What was that about? Then i remembered, when i was still taking architecture, my grandfather asked me why that course? I should have chosen a more respectable job like a teacher perhaps. Since my mother and aunts are teachers. I should have been a teacher too. I don't really understand why he wanted to push education as a course. I have a vast patience like an ocean and that's not even the point. I'm living with a teacher and seen my mother in action. At times, i write her lesson plans but i don't understand why do i have to do something they do too. Is it wrong to be a designer? I know i wanted to pursue the course i have taken and was too picky on jobs but ended up working on another field yet closely related.
I admit, i am unique. its just the way she said it. It was like putting it lightly and meant another. I'm happy being different. But you're making it sound like its a crime. Its enough that I'm already 27 and still stuck here, do you have to rub it in?
