1. Long Hair
Often larger isn't constantly much better. What some ladies view as a giant piece of creative wizard on the top of their heads, men typically see a challenging mane.
2. Mood Swings
It was Katy Perry that placed this so amazingly right into song lyrics: '
Cause you're hot then you're cold
You're yes then you're no
You're in then you're out
You're up then you're down
You're wrong when it's right'
Why the constant modification of mood chicks? United States poor fellas simply can not keep up!
