7. "You Glow In The Dark! You Talk! Your Helmet Does That... *Whoosh* Thing, You Are A Cool Toy." - Toy Story
You can make someone's day by giving them a compliment, even if it's just a 'oh, you look nice today.' Though maybe don't lead with 'Oh, look at you, you've had a wash.' By noticing the qualities in someone else and simply letting them know that you appreciate them, it can go a long way. Even if they can't glow in the dark, let them know that they're still cool. Even if they wear a backpack.
