About my passions I can say that I am an amateur sports I mean practice them (more sports), but not at the level of performance. I really like to ride a bike, play a shampoo and many others for example, to travel especially in the mountains I love to go on hiking trails. I am a family man and I very much want to be united in the family with as few arguments but as many smiles (I'm not saying that there are arguments in me I said as an idea). I can say I like to go out with only my best friends, I like fun and try new things. I'm one of the smartest students in my class. It's very important, in my opinion, how you talk to a person and how you interact with others. I'm a disciplined and calm person, I don't like to get involved in pointless conflicts, especially for a game. In my spare time I like to play football, hang out with friends and spend time in front of the computer. I train at the Football Sports Club "Zimbru Chisinau" i play in the position of defensive midfielder and I love this position. Although I don't practice them at the performance level, I try to keep in shape and have fun through these means.

As hobbies would be cycling and also gaming. I do not practice a high level gaming, hurtce the game that allows me PC. As a rule, I put my heart into everything I do, as long as I'm interested and take into account any advice I've received, no matter who it's given. I'm currently a student at Al. I. Cuza High School of Technology, and I'm in the 11th grade. I'm not so good at putting myself in value with words, I think it's the facts that matter. I'm not the kind of person who's too upset. I'm optimistic and consider myself a lucky person in every way. I love smart people who have an opinion or something to say, but unfortunately these days you rarely see anything like this. That's who I am!
