Dealing with a difficult or "challenging" person...
"Properly attired":
Colossians 3:12
"Therefore, as God's chosen people, holy and
dearly loved,
clothe yourselves with compassion,
kindness, humility, gentleness and patience."
The full armor of God.
Bible study on that here:

Study it often and apply it daily.
*Janny,
She could be struggling with a mental illness... much of
what you have said reminds me of my friend from church
who is a lot like the person you're talking about.
There was a time when my friend nearly went off on this
older lady at church who'd declined to give my friend a
ride because she already had plans and wasn't available
to take my friend where she wanted to go.
The older lady was use to that and handled the situation
beautifully.
The older lady in question had a daughter who struggled
with mental illness...nearly two years ago(?), the woman's
daughter wondered off....there was a big search for her
but unfortunately... bad weather set in and the lady's
daughter died from exposure.
