Yesterday, I received a unknown number call.

She: Wai...Judy ar...regarding the bla bla bla
Me: Sorry, is not Judy here. She is not in..
She: so u are...??
Me: I'm Lily..
She: Ok..Lily..I juz want to check with u, what time ur man will come tomolo?

Me: Oh..like that ar. Ok, I will inform Judy, because she is the one arrange it.
She: Ok..so please let me know the time ASAP ya.
Me: Ok..

Her situation:
Her cabinet's key is lock inside the cabinet...

Since we are the one supply the cabinets for them,
so she called us to solve it.
but, I wonder why she will have my number.....
（肯定是JUDY干的好事！)

Then, I sms to my boss ask her what time the workers will be there tomolo. I mention Michell said be EARLY.
and my boss reply : She think she is the only person busy. tomolo 11am reach.
Ok..then I call back to Michell and tell her AROUND 11 am.

Today, 11am I receive Michell's call
Michell : Lily ar..ur workers not here yet!
Me: Oh..they should be on da way d....

11.20am she called again.
I was on my office phone that time.
Since I din't pick up the call, she call n call again...
Ok, finally I answered.
