One day Juan was walking through the square and when he got to a fast food cart he found a movie ticket lying on the floor, he curiously looked at it and seeing that it was for two people, he kept it in his pocket quickly so that nobody saw him and take his girlfriend. At the end of eating Juan goes home again, but when crossing the street he sees a child crying inconsolably and a very sad mother, when approaching and asking him what happens the mother says "We are poor, but I worked a whole week to fulfill him I dream of my son going to the movies, and now I lost my ticket. Has he seen it by chance? "Juan immediately answered" No "and started on his way, after 5 minutes Juan tormented himself and said to that woman if he had found it, but it is yours, take your son" and that woman with tears in her eyes said "Thank you" and Juan replied "forgive me for lying" and that sweet woman said "always remember, if you're going to lie, keep it short"
