Learn Cantonese fluently

My whole family come from the far east, so my mother tongue is Cantonese. I don’t speak it much now, so its not very good. Just recently went to Hong Kong, and all my relatives were like:
“Why are you so quiet?!”
but I’m not quiet! I just don’t want to embarass myself with my rubbish Chinese!

you have no idea how badly i want do this. i`m progressing slowly .. but, i think i`m learning a bit each few weeks .. so that`s cool. :]
