And yes, alcohol was a factor:

A 36-year-old Michigan man is dead after shooting himself in the head while teaching a girlfriend how to handle pistols.

The Oakland County sheriff’s office says alcohol appears to have been a factor in the man’s death Sunday night in his Independence Township home, northwest of Detroit.

I’m guessing the girlfriend was impressed with the thoroughness of the safety lesson.

Alcohol and gun safety are incompatible. Period.
