I think every shy or quiet person has had the experience of other people getting annoyed at them because they were reserved and untalkative. That's just what they do though, they hang back and don't speak as much. It's not because they're mad, or snobby, or that they're purposely trying to kill the fun vibes in the room. They're just a bit tongue-tied at first and need some time to warm up to the people they're with, or it's their natural style to sit back and observe.


Shy and quiet people hate this. Sometimes the person will say something in a more accusatory, confrontational way. At other times it's more well-intentioned and matter-of-fact. Sometimes they'll make a comment to other people in front of the person, like they're not there. This is Craig. He's nice, but kind of quiet.
Either way, it's kind of thoughtless and annoying. Don't say stuff like that out loud. Also, rather than shaking them out of their quietness, it often makes people feel more self-conscious and misunderstood. Oh, and never, ever comment on someone's shyness like they're a cute, shivering little lamb. Like, "You're shy?

 Shyness makes it harder to think of things to say, but most people have an easy time talking about topics they're interested in. The things to say are already in their brain ready to go. Like if someone likes video games, all you have do is say 'PlayStation 3' and a dozen things will come to their mind. So try to land on one of those interests, and they should have a much easier time talking to you.
