... when you cry at work, because of stress or because of miserable clients. I think it is quite normal though. I have been working at an engineering company for a while now and sometimes the stress is just so bad that I drop my head behind my desk and I let myself have a good cry. Sometimes I go hide in the bathroom to cry! Whatever the case... as long as you don't bottle up your feelings.
We are just human beings FFS! We are not robots!
