Well, a "hobby" is something -- and you can think of the word "habit". I think most of you know "habit" is something you do regularly. Well, a "hobby" starts with a "h", and it means "something you do regularly". But in this case, it's something that's fun, you do it regularly, and you don't get paid for it. That's what we usually call your "hobby". So you might even spend money and time to do it, but you get a lot of fun from it, and you do it regularly. Now, another word for "hobby" is "interest". And the funny thing about "interest" is that I could say to you, "What are your hobbies?" Or I could say to you "What are your interests?" And it's almost the same. And we use them -- English speakers -- almost interchangeably, which means we can just change them, and it doesn't really matter. But there's a slight difference. Remember "hobby" and "habit" go together -- you do regularly? Well, "interest" means "I like it". Like, I'm interested in the theatre, but I don't go all the time, maybe once every two years. But my hobby is collecting comic books, which means I actually -- every week -- buy the comic books. Like, I have it, and I get enjoyment from both. So remember, you can use the words, but one is more specific, all right? So you could say -- you know, you could say, "I'm interested in reading." -- I don't have time to do it, but I like the idea of it. versus "My hobby is reading.", which is -- that's what I do when I don't have anything to do. All right?
