Crave / Yearn What's the difference between crave and yearn?

Presentation Hi, How are you? I'm new in this website. Let me introduce myself to you. I'm Quique, nickname for Enrique, in English Harry lol. I'm 31 years old and I studied a Business Bachellor's Degree in Castellon, Spain. Also, I worked as a bank teller for almost 5 years. Because of the economical crisis, I lost my job and I went to Manchester, UK, where I was living for 6 months studying English and I got the First Certificate of Cambridge. That's means I can speak with fluency, but sometimes I make mistakes. My aim is to get the CAE and for that I need to speak more, spread my vocabulary, try to understand better than I actually do more accents such as Mancunian or Scottish within the English Language. I'm not sure, but may be I will go back to UK soon. I have great friends in there. If you want to make a language exchange, I will be glad to speak with you, teach each other, try to fill our gaps and erase the mistakes. May be we can build up a good friendship. Why not? I would like to speak with English, Scottish, Irish, Welsch, North American, Canadian, Aussie, etc... Besides, if you are learning English and you have a conversation level, it can be great to talk with you full time in English. I can give you my Skype name in order to talk whenever we want Thanks for reading me Quique
