Every morning
My dad watches tv everyday in the morning before we leave the house together for work. He usually watches Channel New Asia for the news and when there’re extra minutes (e.g. when I oversleep and he has to wait for me), the sports channel for football/golf updates.
This morning, I saw my dad switching the tv channel to the one specialising in Chinese dramas, right before he turned off the tv and got ready to leave. I didn’t notice it before. But I’d bet my dad did that every morning.
Because my mom would usually turn on the tv when she wakes up, and her favourite is (of course) the Chinese drama channel.
