We cry tears of emotions. tears of sadness and of being happy.
We sleep 1/3 of our lives away.
Did you know that kissing is an instinct.
We laugh to spread positive emotions to others.
When we blink that clears away dust from our eyes.
I don't think there are any set rules on any of this. I laugh so hard I cry sometimes. Sometimes I sleep half my life away. Kissing is an instinct? Don't think so. Blinking is a good thing to get that dust out.
