What is PROPER ETIQUETTE when wishing to inquire of a fellow y!a user, Just From Curiosity?

For example, if he were
angry
and
a
senior
citizen...

People: Hello..."angryseniorcitizen"
is a fellow P&Ser who I've not
seen for awhile...

Lemme at him, Rockman!

just ask
"hello how are you doing?"

Ummm...I'm not sure. I guess you'd have to be careful you didn't give him a heart attack.

Send him a message in large font.

You must have pissed someone off....
I guess it would be to just email them or leave a comment in one of their questions?

well, uh, Hello.. I've never heard of such a person. Sorry.........

hows the machinery doin, old man

Ask !!!

SAY
Hey
You

Send an a courteous email inquiry.

Just say Hello,
Hoping all is well,
Miss your wittiness !!
Just gotta ask to find out !!

Sorry I can't help you.....
Make that person a contact.....when you find them....
Peace.

well you never can be too careful so you should post the message via courier pigeon... that sounds safe
