I added him back, but took a look at his friends list. mike_l looked familiar from malinear's journal just recently, so I clicked on the name. Sure enough malinear, thedarkbear and prncssvictoria were all in bold in his friends list (meaning we both have them on our friends lists). So I clicked on all nkcmike's friends.
hypatia42 proved the most surprising. Not only malinear and thedarkbear but fairgoldberry and radcliffe. Turns out that hypatia42 is nkcmike's daughter and mike_l is her husband.
I am simply DYING to know how seemingly different circles have met.
