Hobbies are things we like to do in our spare time that make us happy and help us relax and forget about everyday troubles.
Actually because of the studies and taking care of my brothers I don't really have time for hobbies but nevertheless I have hobbies and my favourite ones are surfing the Internet, singing and watching TV.
Surfing the internet is what I mostly do whenever I have free time. Also often visit news websites to read daily news. I also often visit music websites to update new songs. I like it because you can find anything you want in the Internet. I think it's interesting to me 'cause I can know a lot of things about life or just chat with foreigners to improve my English.
Singing is my second favourite hobby. I'm not really good at singing so I do it when I'm alone. I like it 'cause it helps me to forget about all the stress from a hard day. And I'm interested in it because it's a good way to express your feelings just by singing your heart out and putting all your troubles in a song.
The reason I like watching TV is that it also helps me to know more things about life and I guess the main purpose why I'm interested in it is that watching TV is a good way to relax or just to have a laugh. So I often watch comedies or funny Disney cartoons.
In my daily life and studies, sometimes I feel really tired and stressed, and hobbies help me to relax and enjoy my free time.
