It is a positive that W responded to you and acknowledged your hurt over not seeing Woofie. That's a first for W. A baby step, if you will.
Your next step is to re-read my communications with Ms. Wonka in my old Pretty in Pink thread. I seriously think it's high time that you "rip off" some of the script that I used on Ms. Wonka about friendship being not a monopoly. Seriously. I do see a lot of parallels between our convo and the so-called Mexican stand-off on Woofie.
I would re-work the draft and "borrow" some lines from my email response to Ms. Wonka. This is now a PERFECT time to do so and you must do it before the weekend rolls around. Seriously. WTF about having you "dogsit" Woofie for one measly day!!??! And "closure" as in never seeing Woofie ever again? Again...WTF???
I am ready on standby to assist you with this process.
