A lot of people say that Kurt Cobain never washed his hair but they found his Head and Shoulders behind the couch.
Are you making light of his mental illness and suicide?
No, I have an interest in it and I've read about it.
Suicide is typically followed by depression or a traumatic event, and shouldn't be made light of. When you joke about suicide, you trivialize the mental health struggles of the people who committed it, as well as the pain of the families they leave behind. Try to be more conscientious and consider how you would feel if someone joked about your loved one committing suicide.
