Like attracts like is the most common phenomenon in science. A hydrophilic liquid will always attract another hydrophilic liquid whereas a hydrophobic attracts the one of its kind. So whenever two liquids are at a distance from each other, then they always tend to move towards their mother liquid. It is the liquid that has the same chemical properties like them. A hydrophobic liquid always stays away from a hydrophilic liquid and the same holds true vice versa.
