Why isn't Kailyn paying any attention to Meggie?

Oh, Meggie's just her back-up friend. She's talking to Ashley right now.

Secondary Friend 

Secondary Friends are those friends that only interact with you when their "primary friends" (commonly identified as "new friends" or a new social circle) are not available.
Usually normal friends become secondary friends when the friendship is vanishing, a symptom of a friendship about to end, often caused by aquisition of new contacts and/or diminishing interaction between you. Which sometimes can last years because one or both parties does not want to end it.

A: <insert friend name> rarely talk to me nowadays, but suddenly and randomly starts conversations with me.
B:That means you have become a secondary friend to him. His new friends are probably offline when he talks to you.

In many cases your friend will have pictures of themselves with the loch ness friend. Others will have reported seeing the loch ness friend at various locations.

Your friend will arrange for drinks or dinner with the loch ness friend, and the loch ness friend will never show.

Yeah, Scott invited Missy to our housewarming party and several other events and each time she has not shown. I STILL haven't met her. She is the loch ness friend.
