Love is funny

Isn't it funny,
That you can explain how the human body works,
But you can not say the three words,
"I love you"

Isn't it funny,
You can shout to your friend,
Across the street,
But you can even say "hi",
to him or her?

Isn't it funny,
When he or she is beside you,
You try to be cool,
And end up messing everything?

Think about it,
Isn't love funny?
