How Blind is Love to Make Us Stupid ?

This morning as I entered the English Academy where I am working, with headphones on at highest volume, listening to a Spanish crash course, one of my colleague asked me, "Do you know how to speak Chinese?" I answered, "Well just the basic one". I then discovered a young Chinese lady at the couch looking for her lost boyfriend (yeah, this is real! sounded like a TV drama eh). She lost in contact with her Korean boyfriend who had been studying English here in the Philippines. His boyfriend was our student in this academy a month ago, but after that he went out to find an independent tutor. Actually I saw her boyfriend few days past at one of the bar here in the city. We had a few chat and he is doing well and enjoying being a freelance learner, so I told her about that. She waited for the manager (a Korean) of our academy and ask for help where she can find her boyfriend. She lost in contact with him for almost three weeks and there was this speculations I heard that they already broke up, the reason why the guy probably changed his phone number. So what the hell is she doing here? Spending money to fly from China to the Philippines just to find her lost boyfriend? Yet in fact uncertain if her guy still loves her. Is love blind or just so stupid to be blinded? Today she went to the place where she can possibly find him, showing a picture of her boyfriend to anyone if they know him. Well, good luck to her!
