Cliques - Doh!
I can't believe I forgot about that aspect. Thank you AXOKatie and winneythepooh7 for pointing this out.
Two friends rushing together - so to speak - doesn't come across as a clique. Three or more might with five certainly getting in that realm. And frankly, for the most part, cliques are just not desirable.
This is something I will pass on.
Thanks again for all your suggestions and comments.
