Pandarific!!

Ok, when you comment in a c-box and i (mandy) want to reply you, is it normal to reply within my own chatbox or am i supposed to go to you blog and reply in your chatbox? what if the person i want to reply to doesn't have a chat box? see i kinda followed the format/way of this other blogger who replied within her own chatbox in her own blog....i should have asked this earlier i know, but better late than never?
