My cantonese isn't very good either, lol. I only use the basic house-hold stuff. Sometimes my mom just stares at me and tells me she didn't understand a thing I said D; When we go out to Chinatown (way smaller than yours) or when we speak to older Chinese people, I tend to stay quiet anyway.
Doesn't help when my brother makes fun of me whenever I use Cantonese to him... Actually just the other day...
My brother and his gf were talking about something, I was half listening, and then I hear
Brother's gf: Yay! You finally speak in Cantonese to me! (she's from shanghai and learned Canto by watching dramas)
Me: Wait, what? You don't speak to her in Cantonese?
Me: Why not?
Brother: I don't speak to you in Cantonese.
Me: That's because you make fun of me.
Brother: I don't understand your Chinese!
Me: Well I don't understand your English!
Brother: This is why we don't talk much!
I have a cute puppy... almost 3 years old. He's spoiled... but he's still adorable ;o;. <3
