Nick, he very well could. And Ghandi is spot on with what I'm trying to convey here.
Every day we (mental health workers) have to make potentially life or death decisions. It's easy to become complacent when dealing with the suicide attempts that aren't serious/successful. Sometimes they are doing it for attention because that's the only way they know how to get it. But regardless of the motive the attempt within itself is indicative of a problem. It's terribly hard to judge human behavior.
Case in point: A coworker of mine assessed a lady who had superficially attempted suicide and was convinced to come to our walk-in center by her sister. The client initially agreed to stay at our inpatient unit for a few days, but around day 2 she began to state she wanted to go home. Client outwardly appeared fine, even laughed and joked amongst other clients and staff. We didn't want her to go home, but realistically if she was telling us she was fine, contracted for safety,etc (and given her outward appearance) we had no basis to keep her or commit her to a psych hospital. We let her go. This is a lady that a lot of us interacted with at some point during her stay. We all agreed that while it probably wasn't in her best interests to go home, we thought she would be safe.
Wrong. She went home that night, grabbed a shotgun, and almost literally blew her head off at her husband's grave. Ends up one of our Nurse practicioners (who has been in the field for a while) had called her suicidal statements and superficial attempt malingering and accused her of being manipulative.
Even we get it wrong sometimes, which is why it is so important to take every attempt, no matter how trivial or superficial it may seem, seriously.
