Lick things!
Don’t believe me? Here are two examples of how licking things will dramatically improve your outlook:
When I find something that I don't recognize, naturally my first instinct is to use my tongue to identify its origin. Nine times out of ten it’s a pleasant surprise & my day just got better.
If you are looking to enliven your day (and as an added bonus, a friend’s day as well), lick their cheek. I have yet to meet someone who can’t help but smile when they think a sweet intentioned kiss is on the way & instead they get accosted by my lizard tongue.
