What do you need to feed your pets (or your kids for that matter) to ensure that they will always come home?
When I was in Kindergarten I walked home the 2 miles from school. I thought I could go and see my friend's house and be back to catch the bus in time. So, when I got back to the school and discovered EVERYONE to be gone, I did what any reasonable 5 year old would do....I walked home. (I may have even been 4 at the time)
And there are advanatages to being part of a large family...it seemed that even though I arrived 3 hours late, no one even noticed. Talk about empowering...I learned at an early age that I could arrive wherever my feet would take me.
