We often meet someone who gives us the impression that they are interested, they give us that feeling of certainty making us think that we finally found the one.
Sadly, at the same time we forget that for some. It is in their nature to be the way they are, it soon after dawns on us that all the effort we put in was for nothing. Misunderstandings and false hope follows soon after and you wonder why you ever tried.
Save yourself the trouble of ending up in false hopes and painful disappointments, see how they are with others before you decide that they really feel that way about you first.
