If you can’t join the military (because you’re an older woman with a baby, for example), you’d be ill-advised to go around trying to kick anyone’s arse.
However, you can fix them with a killer stare and observe, “Appropriate behavior in this situation includes ...” if you feel lucky.
I’ve done both. Actually, I prefer the latter approach.
This email struck me because my friend is not and never has been associated with the military, and seldom ever voices her political opinion.
After 60 years, I learned something new about her!! :o]
