I had other very interesting colleagues, amongst who was Andy... 
These days, I can only say that describing Andy and his place in my life is not an easy feat...
I´ve felt indifferent to him, he´s driven me nuts, he´s made me mad and there´ve been times when I´ve had to supress an incredible urge to shake him... 
I´ve loved him, admired him even, I still respect him and there´ll always be a soft spot, a special place for him in my heart. Above all, I am and will be very grateful that I met this man, someone who challenges me to be the best I can be... he´s shown to be my number one fan, he believed in me and has helped me to establish an enviable command of the Spanish language. 
At the beginning, it was supposed to be a swap, but most of the time, it ended up being a spanish class, partly because he loved teaching, and by God, he is good at it... and partly beacuse I did want to learn. I won´t say anything about my feeling totally unable to actually TEACH Andy any English..., he always came up with so many linguistic and technical question regarding English... some of which I had not the faintest clue about...and the ones that I possibly knew, I wouldn´t remember. I didn´t mind having a conversation with him in English, but I always backed out anytime he came up with those questions... 

We´ve gone through different phases, but through it all, we´ve maintained a certain respect and admiration for each other, or at least I´d like to think so... 
These days, there´s an unspoken distance between us, but it doesn´t feel bad or worrisome. It´s happened before in the past, but we had mannaged to find our way to our friendship again... I´m hoping that we can always find it again, anytime.
One of the things Andy did for me which greatly endeared him to me was passing over a prospective student of his to me. Hís English was good enough to tutor a young learner or a beginner, but he choose to pass over the opportunity to teach Luna to me. When I met Luna, it was love at first sight, an interesting and exuberant little girl of seven. We hit it off immediately and for 3 years we got along like a house on fire. For 3years, I taught her... she learnt and I loved her.
