  • Haha, I love spooking myself.

  • *turns quickly* What was that?

    August 10, 2007

  • "(imaginary comment)" :oP

    August 10, 2007

  • Ah yes, I had imaginary friends when I was a child--and they weren't even human. :-)

    Jennarenn, I have that cookie recipe, so I'll just bring it along myself. You're sure to get a thank you note from Canada when I return. And one from Granny Smith, no doubt. ;->

    August 10, 2007

  • Aren't imaginary friends great? I always wanted one as a child.

    R, you simply must say hi to Canada for me, and tell them that I'll bring the cookie recipie next time I'm up that way. ;)

    August 10, 2007

  • Oh, Reesetee, you mean I really do have voices in my head, too? In that case, I also wonder why I can't get them all to agree with each other.

    I think I will opt to simply enjoy the illusion.

    August 10, 2007

  • Eh, I might. ;-)

    August 9, 2007

  • It was a memorable conversation, U.

    And R--I feel sure you will fill your suitcase with plenty of Canadianisms!

    August 9, 2007

  • And here *I* thought you'd already seen Granny Smith and was wondering why you were off on another vacation so soon. :-)

    Oh, and slumry? Dear S is right--we are your imaginary friends!

    August 9, 2007

  • All I can say is, I'm surprised and impressed that you remembered and linked next week's trip with the Granny Smith trip I mentioned a while back. I'm terrible at making connections like that. Or rather, the conscious part of me is... but apparently the subconscious part of me excels at it. ;-)

    August 9, 2007

  • *Green with envy*

    August 9, 2007

  • Oh...Canada! ;-> Specifically, the Atlantic provinces.

    August 9, 2007

  • Okay, I am getting separation anxiety now. I will miss you two voices in my head next week. (Dear S calls all of you my imaginary friends). U, give your regards to Granny Smith. R, do you to care to give us any hint of your vacation plans?

    August 9, 2007

  • Really? Mine sing, in a chorus--sort of in a strophe/antistrophe way.

    August 9, 2007

  • Nah, the voices stay. Some just become louder while others quiet down. At least I can only hear a few at a time!

    August 9, 2007

  • Well, if you're going away, maybe the voices will stay put and leave you alone for a while.

    Or me. I can't remember anymore.

    August 9, 2007

  • Okay, don't go away. Just stop disagreeing with the other 6.whatever billion voices. It's the discord that makes it frustrating!

    August 9, 2007

  • Are you sure? It may be very lonely!

    August 9, 2007

  • When the voices in my head go away, I will finally have peace. ;-)

    August 9, 2007

  • Well, he should care--if you are a part of him, he would be diminished by your absence. Says Judge Slumry. So there.

    August 9, 2007

  • Neither do I. And that's what counts.

    If we don't be careful, we'll disappear into myself, and then where will I be? Not that you care.

    August 9, 2007

  • Of course you're not, because I don't want you to.

    August 9, 2007

  • I'm not even going to ask.

    August 9, 2007

  • You can't think about it right now because I have a one-track mind, and my attention is elsewhere. Sorry.

    August 9, 2007

  • I can't think about this right now. And anyway, it doesn't exist. Only I do.

  • Did you mean far-removed fig newton of your imagination?

    August 9, 2007

  • How creative is this far-removed figment of my imagination! I wish I had such command of my conscious mind!

  • "I" made up this word.
