It's depressing when you realize your life is like a Dilbert comic.

Coworker:  Hey, TAB, I need you to do Task A for me and email Unrelated Person and let him know as soon as Task A is finished.

Me:  I already completed Task A.  I sent out an email confirmation on Monday.  I don't even know who Unrelated Person is.

Coworker:  Yeah, he's new.  Can you just do Task A again and tell Unrelated Person?  I just sent you an email about it.

Me:  Wouldn't it be easier to just send Unrelated Person my original email from Monday, stating that Task A was already taken care of?

Coworker:  No.

5 minutes passes.  An email appears in my inbox.  It is from Unrelated Person.  It says, "Coworker, I just found the email stating that Task A was finished this past Monday.  Thanks for following up."

Coworker:  TAB, did you do Task A and email Unrelated Person like I asked?

Me:  Oh, didn't you see Unrelated Person's last email?

Coworker:  Yes.

Me:  ...

Coworker:  Well?

Me:  (Sigh.)  Yes.
