A few weeks ago I was reading something and it was mentioned that the proper format of introducing someone when you plan to provide their rel
ationship to you is to say the person's name first and then the rel
ationship. That is because you want to put the emphasis on their name as their rel
ationship to you is of secondary importance. This all makes sense. And even though I've known this rule, reading it had it in the for front of my mind.
A few days later I was at an event with several family members and a friend and I was the only one in my group who knew the guests so was doing the majority of the introductions.
"Dave, this is Ann, my sister"
"Sue, this is Charles, my husband"
But what I noticed as others were introducing people to me, the information that stayed with me was the last thing said. So if Dave said,
"Hmmmmm, this is Tina, my cousin" I'm now thinking about this being his cousin and not so much that her name is Tina.
I think my brain works on the FIFO method, first in first out.

I'm horrible at names and try to resolve the issue by immediately repeating the person's name to try to get it to stick but if I'm being introduced to a group as in "This is Tina, my cousin, Timothy, her son, and Tommy, her husband" I'm know focusing on their re
lationships and not their names and may not get the chance to repeat their names.
So how important is this rule to you when you are being introduced?
Do you find having the name given to you first is the best way for you to remember it?
Also, do you find it rude to not provide rel
ationship context when being introduced by someone. I had 4 family members with me and one friend. At times when new people (there were around 25 guests at this event) would come up, I would just say
"Helen, I'd like for you to meet Ann, John, Bill, and Lisa. And this is Charles, my husband."
At one point, Ann, my sister, asked me why I didn't tell Helen my rel
ationship. Well, primarily because it really wasn't germaine to anything. Helen is just an acquaintance and probably doesn't care who my relatives are. However, it is likely my DH and I will encounter Helen again so it makes sense to me to clarify that rel
ationship. But is it wrong to not always indicate familial re
lationships?
