Forgot the Milk Again

I promised my mom I'd pick up milk on the way home today, but guess what? I forgot. I saw a cute puppy and stopped to take a photo, I mean, how could I not?, and ended up back at home without it. So now, I'm telling her I was held up by work stuff instead of owning up to my silly doggy distraction. It's such a tiny little fib, but I feel so guilty because she always makes the best cookies with fresh milk and doesn't want them to go dry. Maybe next time, I'll just text from the puppy park and say I'm doing it right now, problem solved! But then again, maybe not, since I'll still have forgotten my errand. Oops.
