Sometimes that would happen,but i am shy when it comes to new people.Like when i go to take my aims test and i walk in the room and i feel like everybody is staring at me and just want to hide.It is a breeze for me to talk to other bronies online.
I used to be shy as well and still am. Just not as much as before. I have learned to laugh at myself whenever I do something stupid and to not let what other people think about me get to me. You will lose your shyness eventually. Don't worry.
