Hi Myoasis89,
I think some people have trouble understanding shy people and they misinterpret the shyness - as you don't like them and that's why they want you to change, so they'll feel more comfortable. If you're happy being introverted then that's okay. When I was a child up to 22 yrs., I was painfully shy and didn't like the way, it held me back. People used to think I was stuck up, but actually I was just scared. I learned to manage my shyness, but I would still call myself introverted though. AS long as you're comfortable with it, then don't care what they say.
