Spanish at Home

Now that I know more Spanish I try to speak it more often, especially at home. I started probably around the beginning of this year. I started saying "si" and small talk like that. And now I'm working on more sentences like "tengo hombre" and ''estoy consado" and larger sentences. I think it's funny because nobody else really knows what I'm saying, but it really makes my mom and dad angry especially when i answer "si" when she tells me something. I just say I'm practicing my Spanish!
