because you've spent so much of your life looking for your kid's stuffed friends. and when you hear the words, "where my tiger" so many times each day that you want to banish tiger from the planet. then when you hear "where my tiger" after tiger had accompanied your troop into Target, all you can do is just stare coldly and then get the kids back out of the car, go back into Target, retrace your steps and keep saying to him "i don't know. where IS your tiger?" and when the lost and found people check the lost and found one more time because you are desperate, and she brings the dirty ragged thing out from behind the guest services wall, you remember how excited you always are when you always find the (blasted) tiger.
