This makes me miss the shit out of my dog. The worst part of college isn't the lack of money, the course work, or the constant hangover that leaves with a never-ending headache. It's getting home from class and not being greeted by your puppy when you walk in the door. The only good part is that you get the warmest welcome possible when you come home on breaks. When I go home for Thanksgiving or spring breaks, my dog welcomes me like I've been away at war for six months and she thought she'd never see me again. She pulls a similar move to the dog above, reaching out and pulling my hand back to keep petting her if I ever stop rubbing her belly.
Long story short, dogs are the shit, so cherish your time around them whenever you can.
