HA! HA! HA! Michelle, that's TWICE in one day. You crack me up. (I wrote back to you in the pregnancy question thread).
My Eurasian Mum was the same - learnt English phonetically by ear. She would often say: "May I enjoy you?" instead of "May I join you?". She mixed up tomatoes with potatoes, and of course couldn’t say “th” so words like “thank you” became “senk you”. Mum oozed charm though, and got away with her broken English. Sounds like your Mum is just the same, Michelle :0)
