Many people want it, and people don't want it if everyone get's it. The person who made it didn't work for it as much as the person he gave it to. It comes in all shapes and sizes, and isn't as valuable if you know you don't deserve it.
In spring I look gay, Covered in a green array, The warmer it gets the more clothing I wear, As the cold grows, I throw away my clothes.
What am I?
