It was like that with the hamsters, the fish, the lizard and the dog. The overwhelming feeling of, "I could kill this thing if I don't take care of it right," was too much for me. So we got rid of them all promptly. Kids, I got down, but animals...forget it.
So if you've made up your mind that you never want a pet then let me give you a little word of advice...
DON'T READ THE BOOK MARLEY AND ME!
Because if you do, you'll not only laugh and cry about a stupid book telling a story about an obnoxious dog, but it will plant this seed of discontent about your current state of petlessness.
And you'll start fantasizing about finding a perfect dog like Emily has and all the loyalty and love and cuddles you'll get from it. And then it's over. You'll find yourself at the Humane Society picking up some drooling dog, that pees on your foot and leaves a slobber trail down your pant leg.
It hasn't happened yet but I can't tell you how close I am.
