real story;
string sender = "william";
Boss: The customer called and told that the feature "X" stop working, and yesterday it was working well. Check the server and the databases and blah blah blah...
(later...)
Programmer: I checked and it's really not working. And it's the same on every server, even on our test version. Are you sure that it was working yesterday?
Boss: I don't know.
Programmer: PLOP!
