Hi..
I used to here when I telephone to the few Business organizations secretary talking..
Hi..IT'S Bob, how can I help you... so now my point is can we use "IT'S"?
Also can we use this word to a human? ex: It's a Cat, where it's going.. so on...
Thanks.
You could pick up the phone and say either:
"Hey, it's Bob."
or
"Hey, this is Bob."
