There was a customer called me
 and, I thought it was one of my friend played joke with me..
 cause it's a Chinese number
 then, our engineer told me, he's one of our customer...
OMG, I felt guilty
I was really really surprised...then, he send his email address to me, and want to know our Wifi LED tube
 And, then, I just now, sent  an email to him, OMG! That was Close!

Really, his voice sounds like my friend,

And, his English is...not like people who speak English as their first language...

Very slow, very clear, very...sounds like We Chinese people speak English, that accent, like Chinese

I spoke in Chinese at first, and he said:" Why you speak Chinese with me?"

Strange...
