When you walk by it you wouldn't buy it. But when you do buy it you wouldn't use it. When you do use it, you wouldn't know that you're using it. What Is It?
**CASKET ** or **COFFIN **
I could seem to mean small water. But in reality if you use it, something will be hot, while not using it, something will stay cold. What am I?
When I am open, I protect you from sun and rains.
When I am closed, I provide support while you walk.
I come in different colors and sizes.
What am I?
