So FI and I work in the same office. There have been a ton of packages coming to us - shower gifts and things we are ordering for the wedding.
So today a package arrives in his name and our office admin put it on my desk thinking it was yet another wedding thing I ordered. I open it and see the word pearls on the packing slip....freaked out and closed it right away. I tried to cover it up and make it look like I didn't open it, but he totally noticed and knew I did.
So I ruined my wedding gift!
