Assorted Acrosstics (2/2)

Taken and not given back
Interesting how it's wasted
Many times not enough of it
Everyone uses it everyday

Red, the color of most of them
Oh, how beautiful every one is
Sharp thorns protect its beauty
Expensive, but so delicate

Something everyone has
Many people choose not to show it
A brain is what you use
Ready to work on a challenge
Thinking hard about things
Sometimes we just don't use it
