When "C" Becomes "X"

I had a quite comic conversation with a Chinese-Malaysian officemate in Yahoo Messenger which left me laughing so hard all day.

(Name withheld for security reasons)

Officemate: Charina
Chari: Yes?
Officemate: Can you help me check this sentence for grammar error?
Officemate: Please refer to attach updated baseline document, according to baseline date.
Chari: *tumbling* Ok. Just give me a sex
Officemate: Huh? U serious? For tat very simple request?
Chari: No lah. Wrong typing mah! I mean, just give me a sec. Not sex!

Potek! Kung bakit kasi nagkatabi ang X at C sa keyboard. Hahaha!

Moral of the story:
Read and confirm that you have typed the correct characters before pressing Enter key. Sometimes, with a stroke of bad luck, even a single letter could easily spell disaster such in the case when "c" becomes "x" in my story. Know your spelling.
