A.M.
I agree that this is perfectly normal. My little girl is not shy but does "act" shy sometimes. I try to "help her with her words" when she gets like this. I think it helps. If I notice that she's looking down or backing away from a situation I'll assess it and suggest how she might handle the situation. "Why don't you tell her your name is Cassandra and ask her what her name is." "Will you go give Uncle Greg a hug if I come with you?" She's learning that all she has to do is tell someone her name to start a conversation, or ask me to come with her into a situation she's not completely comfortable with, etc. Some kids just don't have the "social gene" (I know I didn't!) and need some advice on how to handle certain situations. I wouldn't worry. Alot of adults are like this too - you'd be surprised!
