Eye contact is an important one when you are interacting with others. It could give a complete history about one' s character. However, there are instances where direct eye contact is avoided
INSTANCE ONE : when there is a rule, where everybody has to obey it. But, out of your greed, you have done something wrong to a deserved person. However, you,ve come up in your life because of your under-cut practice. Suppose, that deserved person appears before you later in life. You simply cannot maintain a direct eye contact because your conscience will irritate you about your past.
INSTANCE TWO: when you kiss your partner(not always your partner) passionately, your eyes and other person eyes remain shut.
In the instance one your eyes avoid eye contact because of guilty conscious. In the latter instance, you and the other person travel to the sublime state of ectattsy. Next time you better observe it while doing the act of kissimg. The moment you start observing the other person reaction will be "aiyyae, enna nee punnindu kere". Just try it!
