my pet rat died over a year ago, and my eyes still well up when i think about her...but then i shift my brain to the fun times (which included sitting in her in the hood of my jacket, and walking up to an unsuspecting female & saying "i think there's something in my hood, but i cant reach around, can you check?" (yes, i was doing this in college, i guess the 8yr old boy in me never died) )
so just remember the smiles
