@Casey, 

Next time when you go into the milk store, you can say to the owner:

Nǐ hǎo. Nǐ hǎo ma? (hi! how are you?)
He will be super happy about it.

普通話跟廣東話發音上有顯著的分別，很難混淆。

廣東話的用語千變萬化, 如果你有時間，你要試一試。

There are plenty of free ways to learn Cantonese actually. Most people start by watching television, especially Cantonese songs. You can have a look at the following website:

Maybe that helps. But you are right, the teaching material for Cantonese is far little than that of Mandarin because most do not value Cantonese as much. 

That's the reason Cantonese is listed as an 'endangered' language. =)

I am impressed by your reply. I can really tell you are a language nerd comparative linguistics enthusiast. 

Cantonese has a much longer history than Mandarin. It preserves some features of ancient Chinese (古漢語) , for example, 係 (means yes/ to be) is a common word used in Ming & Qing Dynasty.

Can you explain a bit more about: 

'it’s not initially clear  why 恰 uses 合 as the phonetic, but considering the more conservative Cantonese pronunciation, it makes perfect sense.'

Love to hear your thoughts! 

I have started on mandarin and will learn cantonese when i an fluent in mandarin. I think i chose mandarin because the amount of learning materials available for mandarin far outweighs what is available for cantonese. My approach will be different with cantonese. I will get lessons from the start. If i cant afford lessons then i dont start. if i had done this with mandarin i think i woild be fluent by now

What I miss most is the food in Hong Kong. =) 

Yes, your Cantonese is all correct. 

I love the way Cantonese sounds! I spent the summer of 1990 in Hong Kong & Guangdong, and I still remember the sound of "mut-yeeeah", which I think means "what" :) Also, there was "mm-goy!" which means... thank you?
