I think it's the other way around Johanna! It is nice to be able to pull my hair up into a ponytail but if I want to look more presentable it takes forever!! With short hair I can spend 15 minutes drying and fussing with it and be good to go for a day or two!
The temperature thing is another reason that I want to cut it. If I can handle Japanese summers I can handle anything.... I'm still not looking forward to a hot Texas summer though!!! :p :D
It's already in the 70s and 80s here so no worries about keeping warm :D
