Bye bye Flat world. Hello Spiky world

Pretty obvious on what I'm trying to deliver. :D

Pros of long hair: no need comb, no need style, save hair styling products.
cons of long hair: waste water washing, very "hot", disturb vision, hard to dry

pros of short hair: Not so hot, save shampoo, save water, faster drying time
cons of short hair: need to comb, hair can be identified by looking at the length( at home comparing to mum n sis)
