I'm truly overwhelmed by all of your kind and compassionate responses. I'm especially touched by the personal stories you've shared, and I want to thank everyone who responded - you will never know how helpful you've been. We've decided to go. We're taking a lot of your suggestions to heart and we'll be doing some new things this trip, including making a visit to the kennel. We're going to look for small ways to spread some pixie dust to strangers, in the hopes that someone else's happiness will ease our grief.
Thank you so much, every single one of you. I've always enjoyed reading the DIS even though I don't post very often, and I knew it was a special community - I just didn't realize how special until now.
