I had just started a new job and was still getting used to the email system. I received an email from my boss and wanted to respond, but accidentally hit “Reply-All” instead of “Reply.” My response? “Sounds good, can’t wait to start working with you!” was sent to everyone in the company, including the CEO. Needless to say, I was mortified. But it could have been worse – at least I didn’t accidentally attach a picture of my cat.
