AS and I email each other while at work sometimes. Both of us are so busy someday that the only way to talk is via email. Sometimes it is a few words depending upon the context. Here is one of the funny email chains.
My email (After forwarding an email): OK. I have sent you John’s email. Please read.
AS’s email : Where?
My email: Yahoo
AS’s email: What yahoo… where did you send me John’s email? To which of my email ids?
My email: Ur yahoo email
AS’s email: hahahahaha, just had a brain fa*t!
He just made my day and I still laughed when I read the email chain again this morning.
