I know I always croon about Penny's latest (if only you knew how much I held back. Thank my brother for that, who begged me not to become "one of those people"), but having spent quite a lot of time with her this summer, she has taught me a few things.
Don't worry about getting dirty. Hell, if there's a puddle there, go for it. If the mud's there, don't be an adult--splash in it! You can wash your clothes and yourself later.
Love with your whole body. Light up when that person you loves comes home or even into the room. You may want to wiggle your behind in delight; I leave this up to you. Go ahead and greet that person with kisses. Lots of them.
Eat when you're hungry. Otherwise, it's not necessary. But find yourself good, healthy things to snack on in the meantime...as long as it doesn't require replacing anything expensive.
Go on walks with friends. Everybody benefits. And there might be fun puddles to jump in.
Play well with others. If someone snaps at you, you need to figure out whether to snap back or turn and walk away. Otherwise, just have fun.
Take naps whenever you can. Self-explanatory.
Enjoy life every day.
I don't care if this sounds corny. I like it, and this picture of a filthy, happy dog says it all:
