I haven't lost a dog since I was about 5.  I think our loss broke my dad's heart, though he'd never admit to such a thing, so I never had a real opportunity to know what loving a pet is all about.  However, though I haven't loved a dog in many years I have LOVED.  So on that level I guess I can understand.

I always enjoy having you along and will enjoy whatever time you're able to share in the future.
