Why do we date? Is it only for fun for a day to find out if we can find someone to partner with us for a long time? If we are looking for fun for a day, we should make this clear to our date and let them not expect anything else. Otherwise it can hurt a human being. If we are looking for a long-term relationship, every lie will ultimately get exposed. That will hurt us even more.
We might be feeling very uncomfortable during a date. Is it better to say that you are enjoying yourself or to diplomatically say about the real feelings? By lying here, we are giving wrong expectations to the other person. Why does that? One can diplomatically say - I am not feeling very comfortable. Can we cut short today?
Some people are liars by habit. They rarely speak the truth and lie as a matter of habit. Such people give wrong ideas to their date and hurt him or her. That is not a good way of doing things. One may not be very truthful, if something embarrassing comes up. But one can surely change the subject or keep quiet. Why lie?
Lying hurts not only during dating, but also in every situation in life. A liar always feels threatened that the truth will one day get exposed. Isn't it better to keep quiet or speak truth?
