Apparently, there's a perfectly good explanation for the momentary weirdness I experienced last night.  Whew!  That's a relief.  When you're on your "friends" page, all their recent entries show up on a page that looks like yours -- for reading convenience.  Not a bad idea, but maybe it should come with some kind of a warning??? 

My computer's been kind of loopy lately, and so anything that happens without some sort of explanation starts a little bubble of panic in my heart!

Gotta' run for now -- my washing machine is calling my name . . .
