Got "S" ?

I have a ABC friend, this one different, he is borned Alor Setar...Lately El started yapping, kept " day day day"...may be she borned in here, she does not go with Pa pa Ma ma, go with daddy? I don't know...anyway recently found the day day is actually something else from El...
Yesterday, spoke with one of my coworker...she pointed out chinese don't usual pronoun the word with "S"...Since we all know chinese got no "S".....errrrr, I mean the "Ssss" sylabus...I usually say, "she work in here". I would have hard time to say " She works(sss) in here". Hoi Pee, where is your S??? Emmmm, listen carefully, chew slowly...let's find more about the S...you think those angro got "S" ? Once again, chinese got no "S"...who does?
