So, the biggest challenge that I've ever faced, I can say, we had a client, he came, and he was supposed to meet the boss, but the boss was not there that day. It was something about taxes, because we were providing taxes, and then it was a document that was supposed to be translated, because we used to provide that too, and he came, and he was very mad, very frustrated, and he didn't want to talk to nobody, so when I first came and asked him, how's your day going, he didn't want to answer, he was like, I just want to see that person. I was like, he's not here today, but he was like, you cannot solve my problem, he cannot handle my problem. I was like, I can handle your problem, yeah, and I was like, take your time, you know, I was like, oh, the weather outside is, you know, it's very hot today, so let me have the AC on, it's going to help you, you know, to calm down a little bit. And I have the AC on, and I was like, do you mind if I provide you water? And I bring him water, he was like, I don't know why, I was like, okay, no problem, and I was able to talk to him, and communicate with him, ask him what he would want, take some mail, and find out his file, I was like, your file was never missing, we have your file here, yeah, it was just a misunderstanding going on, he was like, no, they lost my file, I was like, we never lose your file, I have your file right here, and I pull up the files, and then, and like, you know, find a good way to finish everything that he needed, and then I was on the phone with my boss, you know, just, you know, getting everything done on time, and just to let him know that we had it done before you come, so it was just a misunderstanding, and then I provided everything he needed, and then he was asking for forgiveness, he was so sorry, because he was so mad, and then, I was like, yeah, it's okay, I got you, it's no problem, and we're here to help you, no matter what, and then, since then, he became a very positive person, he became the coolest person ever, yeah, he was like, okay, I should control my, you know, my actions, and all of that, I was like, it's okay, it's part of life, so I understand you, yeah, I don't take that, you know, I don't take it serious, and luckily, I was able to make his day, and then he was cool, and since then, he started giving me everything he had, because, like I said, I always keep myself positive, I don't take things, you know, serious, that.
