I wasn't looking for them. My 10 year old has an email account that he never checks. My aunt sent me a message saying that she had sent him something. I went to his email account, and there are sent emails in his account that my husband wrote.
Really was not looking for anything. Shocked that he would use our son's email for anything related to this.
The emails were innocuous. Anyone looking at them wouldn't see anything much, but there they are nonetheless.
I do love the advice of don't torture yourself. Everything I know I have found out accidentally. I would love to stop having these awful surprises.
