iTalki.com is a straight page website where you can meet people to learn a foreign language. Most of them probably have the same purposes of are probably there for the same reasons as you: to learn and to teach. Nevertheless, I have realized that you must be careful, specially if you are a young person and meet another person of your age. I won't talk about the dangers of meeting a molester [sexual predator] via the Internet, but the misunderstandings and inconveniences that you can find encounter if you aren't discreet in you addressing conversations with opposite sex friends of the opposite sex on iTalki.com, and what you can do to prevent yourself from them avoid them. 

     What are the problems that you can find may have? First, you could hurt someone or be hurt. While you are young, it isn't hard to fall in love with someone else, mainly especially if he/she is are good-looking and well-mannered. If you or your language partner are so --at least in part-- and you take a lot of time talking amongst yourselves, one of you surely will fall in love with the another one. Why? Among young people it's common to have love fantasies and some difficulty to controlling their feelings. Beside that, Internet communication makes it easier to establish bonds of affection among between two people, maybe for privacy on them and possibly due to its intimate nature, this facilitates to talk makes talking about your feelings without so much easier obstacles so than with face to face communication. If only one of you fell in love, and the another one did not, surely the first one will be hurt. But, if the two feel the same? The issue would be better, but even so, you could have problems. I will talk about that in the next reflection. For now, and taking in account what I've written, I would give you the following suggestion: Don't show any romantic indication if you don't feel it. It means aren't stop talking all the time with one single friend, nor do it daily. Equally, don't talk with your friend about very personal things, like if he/she was they were of your same sex. Neither address him/her them like as if he/she was they were your shoulder to cry on.

     I don't want to look like a "Pharisee" writing about all this. I only want to make better improve my writing skill at writing talking about things could be useful. On the other hand, I meditate [value this] in this because I want to treat my opposite-sex language partners in the appropriate way. I read about this in a good magazine and it was very handy for me (I had liked to remember that wish I had this information before). I hope this helps you also to deal these matters correctly.

Very well-written. I would tell you to consider, in the future, using the First Person-Plural voice in your writings. It does tend to be make reading awkward when written in the Second Person. Great job, Héctor.
