This is about a fence. You may be looking for the sport of fencing.
A fence is something built like a low wall, often made of metal or wood, to keep something in or to keep something out. They are always outside. Fences can be painted many colours and shapes and sizes. Some fences are very big whereas others are not. They are mostly used in gardens but can sometimes be used in different places.
Fences are mostly wooden but it is less likely to find metal or any other sort of materials. Sometimes you can find massive fences whereas some are not so big. It is very common that you can get a blister from wooden fences as the wood is kind of sticking out. when you get a blister it really hurts and can cause dripping of blood.
