Why am i shy around certain people

Question

some times i will meet people for the first time and be perfectly comfortable and other times ill be shy, when i start out being shy with people i feel like i cant just suddenly open up to them, any advice

Answer 1

it happens to everyone. you probably just pick up on whether they are friendly or not.  no one ever said you had to like everyone you meet.  as long as you are respectful there's no problem
