I cant believe I hit reply all instead of reply when sending an email.
Oh no, this is a classic office disaster story. How bad was it?
I was complaining to my boss about another employee and I accidentally sent it to the whole company.  I cant believe I did that.  Im glad its the weekend.  I dont want to go back there
Ah heck, I hate that for you. Hopefully it isn't as bad for you as it seems, but just know that that mistake has happened to several people that I know of, so you're not alone.
