Filled with water, ice and anything liquid and drinkable, but never overflowing. A waterbottle a convenient invention indeed. As ones shadow I can list the amount of times it's been useful.
1. Going to the gym
2. Not wanting to clean a glass
3. Any kind of sport
4. etc.
Useful isn't it? There is one thing I don't quite get about certain waterbottle users... Why get up to get a sip from it when you could bring it over to oneself? If I had a mouth I could ask but once again I'm a shadow, so there's not much I can do concerning that. I don't have any problems or frustrations in my life otherwise. My life is, simply put, boring.
