Ontological study says that love hate relationship exists among colleagues. Especially if there is difference in education qualification or skill sets. However, they may have a natural affinity towards each other because of common family, cultural values. Their mutual trust and respect may be extremely strong.

Such colleagues end up in constant conflicts and at times becomes irreparable too. however, if one initiates a subtle patch up, the patch up happens quickly and everything is restored to normal.
