I always thought that shy individuals had a tendency to be treated pretty respectlessly.
I mean, I've experienced this myself back in the day, when I was really silent and didn't speak much.
Whenever I tried to say something, and I actually spoke pretty loud and clear, someone else would start talking and take no notice of me.
I usually just fell silent and sighed, and waited for the other one to finish.
Sometimes this really got on my nerves, and when someone would interrupt me I would go "ahem, I was talking, wait for your turn", and they would go "ok, ok, are you mad, or something?"

It also seems to me that shy people are treated like crap, as if their acquaintances take for granted that they can act anyway they want, like they could mention something in a rude or indignant way.

If a "shy" person gets angry or irritated, then the person will most likely be considered "weird", "mad" or something; but if a respected person gets angry, then it's completely alright.

Do you recognize this? :rolleyes2
