I guess that's why I never saw it as "putting my life on hold" when one of my companion animals needed me. They are such a huge part of my life; they have brought me enormous joy and tremendous love. It's not me putting my life on hold for them - it's me wanting to be with them and return the love they so generously provided to me.
I guess they put their lives "on hold" for us every day. Every time we leave them (go to work, trip to the store, trip to Disney World), they wait, patiently and lovingly, for our return. And while they may pout a bit about our time away, they never hold it against us.
It's the very least I could do to pay a small portion of that back. And, in return, I am rewarded 1,000-fold for it.
They are angels, in my eyes, sent to show us what true love really means. I learn something from them each and every day.
