I work in a sea of cubicals with absolutely no privacy. I was on the phone with someone I do business with to discuss an account. I said out lout "I usually talk to Jane about this account,and she wanted to wait until she got back from maternity leave".
I get off the phone and the guy who sits behind me jumps up, gives me a totally puzzled look and says "you are going on maternity leave?!?!?!"
My face turned bright red - I am a horrible liar. I totally tried to play it off and tell him what actually happened. Luckily he didn't say it loud enough that I had to explain to the entire office.
