Actually, now that I think about it, my BF has done it too a couple of times. I recognized him one of the times, but not the next time or 2. He was surprised I didn't know it was him because he apparently threw something into his comment that I would pick up on. Uh . . . no.
My daughter too. This last time she called herself "D. B. Mergle Gurgle" and I replied to her as D.B.M-G - . She laughed and posted again - Mom! That was me! She thought I would catch the D.B. which are her initials. Uh . . . no.
Now I'm starting to wonder if my son has done it . . . no, pretty sure he couldn't be bothered. Okay well, I'm on the lookout now. But really - it's not much of an accomplishment to put something like that over on me. Afterall, I have been known to be easily confused and distracted by shiny objects.
Is this something that happens to other people - or is it just me?
