Im not sure i really understand the problem. If you enjoy conversing with people even though usually you're quite reserved - thats fine. You can't chat all the time and besides not everyone likes talking a lot - or being talked too a lot! If people like you and enjoy conversations with you im sure they will be alright with you not being as chatty as others - maybe explain to those closest to you that you've always been this way and that they shouldn't be offended by it. Im sorry if ive misinterpreted the question. All the best.
