I don't watch TV very often because i am always busy . If i watch TV, i usually watch for about an hour, and I usually watch TV in the evening, because I am free then. Of course, I never eat and watch TV at the same time, my mom does not like that. I like watch TV Programmes about learning. It helps a lot in my Studies.
