Why do two icecubes freeze to each other in a glass of water?

If i place two ice cubes in a glass of water, after a short while they will be stuck together. Why does water between them freeze to connect them?

Usually ice is done at -20°C.. when you put them in water they can suck up heat from the surrounding layer of water so, before they melt, they can freeze a thin layer of water. If the layer is thin enough (cubes touching), the ice they create is enough to glue two of them.
